Most students preparing for the Class 9 Maths SA1 exam in AP and Telangana do not realise that Mathematics is split into two separate papers at this level. Paper 1 and Paper 2 cover different chapters and are conducted as separate examinations. Preparing for only one paper is one of the most common and most costly mistakes students make.
The 2018-19 SA1 Maths papers are among the most searched previous year papers because the 2018-19 academic year was a transition year for AP and Telangana SCERT. The CCE (Continuous and Comprehensive Evaluation) pattern with its Part A written exam and Part B internal assessment had been in use, but question structures were being refined. The 2018-19 papers offer a reliable and directly relevant preparation reference for students even today.
This guide covers both Paper 1 and Paper 2 of the 2018-19 SA1 Maths exam in complete detail. It explains which chapters each paper tested, how marks were distributed section by section, where to download the original papers with answer keys, and how to build a targeted preparation plan using these papers.

Paper 1 and Paper 2: What Each Covers and Why the Split Matters
AP and Telangana SCERT splits Class 9 Mathematics into two papers at the secondary level. This is different from most other boards where Maths is a single paper. Understanding the split is the first step to effective preparation.
| Paper 1 | Paper 2 | |
| Focus Area | Algebra, Number Theory, Coordinate Geometry | Geometry, Triangles, Statistics |
| Nature of Questions | More numerical and procedural | More proof-based and conceptual with some numericals |
| Chapters (2018-19 SA1) | Real Numbers, Polynomials and Factorisation, The Elements of Geometry, Lines and Angles | Linear Equations in Two Variables, Coordinate Geometry, Triangles, Statistics |
| Marks | 60 (Part A) + 20 (Part B) = 80 | 60 (Part A) + 20 (Part B) = 80 |
| Common Strength | Students who are strong at calculation and algebra tend to score higher here | Students who are good at logical reasoning and step-by-step proof tend to score higher here |
| Common Weakness | Polynomials factorisation tends to trip students who skip practice | Triangle congruence proofs are the most common source of marks loss |
Paper 1 Chapters and Chapter-Wise Analysis: SA1 2018
Chapter 1: Real Numbers
Real Numbers is the foundational chapter of Class 9 Maths and consistently produces questions in every section of Paper 1. In the 2018-19 SA1 paper, this chapter contributed to the objective section (Part A Section I), short answer questions and at least one long answer question.
| Topic Within Chapter | Question Type in 2018 SA1 | Marks |
| Rational and irrational numbers: identification | Objective (1 mark) | 1 mark |
| Representation of real numbers on number line | Short answer (2 marks) | 2 marks |
| Operations on real numbers: simplification | Short answer (2-4 marks) | 2-4 marks |
| Laws of exponents with real numbers | Short answer and long answer | 4-8 marks |
| Decimal expansions: terminating and non-terminating | Objective and short answer | 1-2 marks |
Chapter 2: Polynomials and Factorisation
Polynomials is the highest-marks chapter in Paper 1 across most AP and Telangana SA1 papers. The 2018-19 paper had factorisation problems in the long answer section which required both the factor theorem and algebraic identities.
| Topic Within Chapter | Question Type in 2018 SA1 | Marks |
| Degree, zeroes and type of polynomial | Objective (1 mark) | 1 mark |
| Remainder theorem: find remainder without division | Short answer (2-4 marks) | 2-4 marks |
| Factor theorem: determine if given value is a zero | Short answer (4 marks) | 4 marks |
| Factorisation using algebraic identities | Long answer (8 marks) | 8 marks |
| Division algorithm for polynomials | Long answer (8 marks) | 8 marks |
Chapter 3: The Elements of Geometry
This chapter serves as a bridge between algebra and formal geometry. In the 2018-19 SA1 Paper 1, it contributed mostly to the objective and short answer sections rather than the long answer section, making it a quick-win chapter.
| Topic Within Chapter | Question Type in 2018 SA1 | Marks |
| Euclid’s definitions, postulates and axioms | Objective and short answer | 1-2 marks |
| Equivalent versions of Euclid’s fifth postulate | Short answer (2 marks) | 2 marks |
| Point, line, plane: Euclid’s definitions | Objective (1 mark) | 1 mark |
Chapter 4: Lines and Angles
Lines and Angles is both a Paper 1 and Paper 2 topic at Class 9 level. In the 2018-19 SA1 Paper 1, it appeared in short answer questions with numerical proof questions. Students who could write angle relationship proofs in clear steps scored full marks here.
| Topic Within Chapter | Question Type in 2018 SA1 | Marks |
| Complementary and supplementary angles: definitions | Objective (1 mark) | 1 mark |
| Linear pair, vertically opposite angles: proof | Short answer (2-4 marks) | 2-4 marks |
| Parallel lines and transversal: angle relationships | Short answer and long answer | 4-8 marks |
| Angle sum property of a triangle | Short answer (4 marks) | 4 marks |
Paper 2 Chapters and Chapter-Wise Analysis: SA1 2018
Chapter 5: Co-ordinate Geometry
Coordinate Geometry is a chapter that students tend to underestimate. In the 2018-19 SA1 Paper 2, it appeared in both short answer questions (plotting points, identifying quadrants) and one long answer question (distance formula application).
| Topic | Question Type in 2018 SA1 | Marks |
| Cartesian plane: axes, quadrants, origin | Objective (1 mark) | 1 mark |
| Plotting points in all four quadrants | Short answer (2 marks) | 2 marks |
| Distance formula: calculate distance between two points | Short answer (4 marks) or long answer | 4-8 marks |
| Midpoint formula application | Short answer (4 marks) | 4 marks |
Chapter 6: Linear Equations in Two Variables
Linear Equations in Two Variables is the algebra-heavy chapter in Paper 2. The 2018-19 paper had graphing problems and solution set problems in the long answer section. Students who practise plotting lines on the coordinate plane consistently score well here.
| Topic | Question Type in 2018 SA1 | Marks |
| Identifying solutions of a linear equation | Short answer (2 marks) | 2 marks |
| Graph of a linear equation in two variables | Long answer with graph (8 marks) | 8 marks |
| Equations of lines parallel to axes | Objective and short answer | 1-2 marks |
| Word problems: framing linear equations | Short answer (4 marks) | 4 marks |
Chapter 7: Triangles
Triangles is the highest-marks chapter in Paper 2 and the most demanding. Congruence proofs require students to state the correct congruence rule (SAS, ASA, SSS, RHS, AAS) and write a structured proof. The 2018-19 SA1 paper had at least two long answer proof questions from this chapter.
| Topic | Question Type in 2018 SA1 | Marks |
| Congruence of triangles: SAS, ASA, SSS, RHS, AAS rules | Short answer and long answer proof | 4-8 marks |
| Isosceles triangle theorem: angles opposite equal sides | Long answer proof (8 marks) | 8 marks |
| Inequalities in a triangle | Short answer (2-4 marks) | 2-4 marks |
| Properties of equilateral triangles | Short answer (4 marks) | 4 marks |
Chapter 9: Statistics
Statistics at Class 9 level covers data representation and measures of central tendency. In the 2018-19 SA1 Paper 2, Statistics contributed one long answer question on mean, median or mode calculation plus a bar graph or histogram drawing question.
| Topic | Question Type in 2018 SA1 | Marks |
| Collection and presentation of data: frequency table | Short answer (2 marks) | 2 marks |
| Bar graph, histogram, frequency polygon: draw and interpret | Long answer (8 marks) | 8 marks |
| Mean of ungrouped data: calculation | Short answer (4 marks) | 4 marks |
| Median and mode of ungrouped data | Short answer (4 marks) | 4 marks |
Section-Wise Marks Pattern for Each Paper (CCE Format)

Chapter-Wise Preparation Strategy Using the 2018 SA1 Maths Papers
Real Numbers: Build Speed on Simplification
- Practise simplifying expressions with surds and exponents until you can solve them without looking at formulas. These appear in both Section II and Section III.
- For irrational numbers, practise locating square roots on the number line using the spiral technique. This is a common short answer question.
- Laws of exponents problems require knowing seven standard rules by memory. Write them out without reference and practise applying each in two examples.
Polynomials: Master the Factor Theorem and Identities
- The factor theorem method has a fixed three-step format: identify the zero, verify using the theorem, then factorise. Practise this sequence with at least eight different polynomials.
- Algebraic identity factorisation uses six standard identities. Practise recognising which identity applies before attempting the factorisation. Identification errors are the most common mark loss in this chapter.
- For the long answer division algorithm problems, write the division in the standard format used in the textbook. Do not use shortcut methods as they do not match the expected answer format and lose step marks.
Lines and Angles: Write Proofs in the Standard Format
- Every angle relationship proof in Class 9 follows the same format: Given, To Prove, Figure, Proof (with reason for each step). Practise this format until it is automatic. Proofs that skip the reason column lose 1 mark per step.
- For parallel lines problems, draw the figure with all given information labelled before starting the proof. This prevents common errors in identifying which angles are being used.
Triangles: Congruence Proofs Are the Key to Paper 2 Long Answers
- Learn all five congruence rules (SAS, ASA, SSS, RHS, AAS) with one example of each. Write the rule statement precisely as given in the textbook. Paraphrased rule statements lose the rule marks.
- For isosceles triangle proofs, practise the standard two-column proof format with Statement and Reason columns. This is the format expected by AP and Telangana SCERT examiners.
- Work through at least five different congruence proof problems from the textbook exercise before attempting the 2018 paper. Proofs are the only question type where seeing the full worked solution before attempting is beneficial.
Statistics: Practice Graphs and Calculation Together
- Histogram drawing is always a long answer question in Statistics. Practise drawing a histogram with correct scale, axes, labels and shading. A histogram without a title, scale or axis labels loses presentation marks.
- For mean calculation, the formula is straightforward but errors in the frequency table setup are common. Always make the frequency table first, multiply f and x, sum both columns and then divide. Do not shortcut the table.
- Median and mode calculations are fast if you remember to arrange data in ascending order first. Students who forget this step consistently get the wrong answer.
How to Use the 2018 Papers for Exam Preparation
Step 1: Download Both Paper 1 and Paper 2
Download both versions in your medium from tlm4all.com or schools360.in. Keep the answer keys in a separate file. Label each file clearly so you do not accidentally view the key before attempting.
Step 2: Solve Paper 1 First on Day 1
Solve Paper 1 under timed conditions: 2 hours 30 minutes, no textbook, no notes. Attempt all MCQs first. Then work through Section II, III and IV in order. Show all working for every numerical. Write reasons for every step in any proof question.
Step 3: Check Paper 1 and List Errors
Use the answer key and Principles of Evaluation to check Paper 1. For each wrong or incomplete answer, write down the chapter name, the specific error made (wrong formula, missing step, incomplete reason) and the correct approach. This error list is your revision guide.
Step 4: Revise Weak Chapters From Paper 1
Spend one full study session revising only the chapters where you lost marks in Paper 1. Focus on the specific error types you identified. Then reattempt the same questions without any reference material.
Step 5: Solve Paper 2 on Day 3
After completing Paper 1 revision, solve Paper 2 under the same timed conditions. The two-day gap between solving papers is intentional. It allows Paper 1 revisions to consolidate before you test Paper 2 skills.
Step 6: Check Paper 2, Build Combined Error List
Check Paper 2 with the answer key. Add Paper 2 errors to your existing list. At this point you have a complete picture of your weak areas across both papers. This combined list drives all remaining revision before the actual SA1 exam.
Step 7: Do a Final 30-Minute Review Before the Exam
On exam eve, read through your error list only. Review the formula sheet for Real Numbers and Polynomials. Read the five congruence rules one more time. Do not attempt new problems the night before. Familiarity with your weak areas, not new practice, is what helps most at this stage.
Mistakes Students Make With the 9th Class SA1 Maths Paper
| Mistake 1 | Preparing for only one of the two Maths papers. Both Paper 1 and Paper 2 are equally weighted. A student who scores 55 out of 60 in Paper 1 but only 30 in Paper 2 ends up with a combined Part A score of 85 out of 120, which is significantly below potential. Both papers need equal preparation time. |
| Mistake 2 | Not showing working in numerical answers. The Principles of Evaluation for AP and Telangana SA1 Maths allocate step marks. A correct final answer without working earns only 1 of 4 or 1 of 8 marks. Showing every step is not optional. |
| Mistake 3 | Writing triangle proofs without the Given, To Prove and Proof format. Examiners follow the standard two-column format. Answers written as paragraphs without the proof structure lose format marks regardless of whether the reasoning is correct. |
| Mistake 4 | Skipping Statistics because it feels like a separate topic. Statistics contributes 8 to 10 marks in Paper 2 through the histogram or frequency polygon drawing question alone. The drawing question is one of the most marks-efficient questions to prepare because it is predictable and formula-free. |
| Mistake 5 | Practising only the 2018 paper without solving the 2017 paper as well. The 2018-19 SA1 paper is one data point. Using it alongside the 2017-18 paper reveals which chapters consistently appear in long answer questions, which question types are fixed across years and where the paper setters most commonly place the highest-marks questions. |

Frequently Asked Questions
Where can I download the 9th class SA1 Maths question paper 2018?
The 9th class SA1 Maths question paper 2018-19 for AP and Telangana boards can be downloaded from tlm4all.com (Paper 1 and Paper 2 in Telugu Medium and English Medium), schools360.in (year-indexed archive), apteachers.in (with Principles of Evaluation answer keys), educationobserver.com (AP SA1 previous papers thread) and paatashaala.in (answer key sheets with full solutions). All are free PDF downloads.
What is the difference between Paper 1 and Paper 2 in 9th class SA1 Maths 2018?
Paper 1 covers algebra-based chapters including Real Numbers, Polynomials and Factorisation, The Elements of Geometry and Lines and Angles. Paper 2 covers geometry and data chapters including Linear Equations in Two Variables, Coordinate Geometry, Triangles and Statistics. Both papers are conducted separately with equal marks weightage as part of SA1.
Which chapters are covered in 9th class SA1 Maths 2018-19?
The SA1 covers the first half of the annual syllabus. Paper 1 chapters are Real Numbers, Polynomials and Factorisation, The Elements of Geometry and Lines and Angles. Paper 2 chapters are Linear Equations in Two Variables, Coordinate Geometry, Triangles and Statistics. These chapters form the Term 1 portion of the AP and Telangana SCERT Class 9 Maths syllabus.
What is the marks pattern for 9th class SA1 Maths under the CCE pattern?
Each paper carries 80 marks total. Part A is the written exam carrying 60 marks and consists of Section I (MCQs, 10 marks), Section II (short answer, 8 marks), Section III (short answer, 20 marks) and Section IV (long answer, 16 to 24 marks). Part B is internal assessment carrying 20 marks and includes project work, oral activities and written assignments evaluated by the subject teacher.
Is the AP and Telangana 9th class SA1 Maths paper the same?
No. AP and Telangana have used separate SCERT textbooks since the 2014 bifurcation. While the paper format (two papers, four sections, CCE pattern) is identical, the specific questions, chapter sequence and some content differ between AP and Telangana versions. Always download the paper matching your state board. Both versions are available separately on tlm4all.com.
Are answer keys available for the 2018-19 SA1 Maths papers?
Yes. Answer keys and Principles of Evaluation for the 9th class SA1 Maths 2018-19 papers are available on apteachers.in and paatashaala.in. These keys include the expected answer for each question and the step-mark allocation for numerical and proof questions. Schools360.in and tlm4all.com also link to teacher-prepared answer keys for both Paper 1 and Paper 2.
How many marks does the long answer section carry in Paper 2?
Section IV (long answer) in Paper 2 has three questions of 8 marks each. Students answer any two, giving a total of 16 marks from Section IV. In the 2018-19 SA1 Paper 2, the long answer questions came from Triangles (congruence proofs) and Statistics (histogram drawing plus mean or median calculation). These two chapters together accounted for the bulk of the long answer marks.
Can I use the 2018-19 SA1 paper to prepare for current year SA1 exams?
Yes. The AP and Telangana SCERT Class 9 Maths syllabus for SA1 chapters has remained broadly consistent since 2018. The CCE paper pattern with Part A and Part B also remains in use. The 2018-19 paper is a directly valid preparation resource for current year students. If your school has issued a revised syllabus circular for the current year, confirm the SA1 chapters with your Maths teacher before relying solely on the 2018-19 chapter list.
How much time should I allocate to each section in the exam?
A recommended time plan for the 2.5-hour Part A paper is: Section I MCQs 15 minutes, Section II short answer 15 minutes, Section III short answer 45 minutes and Section IV long answer 55 minutes with 10 minutes remaining for review. Practise this timing using the 2018 paper before the actual exam. Most students run out of time in Section IV because they spend too long on difficult Section III questions.
What is the most important chapter to focus on for Paper 1 and Paper 2?
For Paper 1, Polynomials and Factorisation is the most marks-critical chapter. It contributes to Section III and Section IV and requires both factor theorem knowledge and algebraic identity application. For Paper 2, Triangles is the most marks-critical chapter. Congruence proofs appear in both Section III and Section IV and require precise proof format. Mastering these two chapters before the exam secures approximately 30 to 40 percent of Part A marks across both papers.
