When students search for the 2018 8th class Maths question paper, they are not all looking for the same paper. A student in Andhra Pradesh needs the AP SCERT SA1 paper. A student in Rajasthan needs the RBSE annual exam paper. A CBSE student from Delhi needs either the SA1 or SA2 from their specific school. A Kerala student needs the SCERT annual examination paper.
Every one of these boards tested Class 8 Maths differently in 2018. The chapters they covered, the marks they allocated, the question formats they used and the duration of the exam all varied. Using the wrong board’s paper is a common and costly mistake that gives students a completely inaccurate picture of their preparation.
This guide covers the 2018 8th class Maths question paper for every major Indian board in one place. Each board gets a dedicated section with chapters, marks pattern, a topic-level analysis and verified download sources. By the end of this page, you will know exactly which paper to download, what it covers and how to use it effectively.

Cross-Board Chapter Analysis: What Every 2018 Paper Tested
Looking at the 2018 Maths papers across all five boards, several chapters appear consistently regardless of board. These are the highest-priority chapters for any student using the 2018 paper as a preparation reference.
| Chapter / Topic | Boards That Tested It in 2018 | Why It Appears Everywhere |
| Rational Numbers | CBSE, AP, Telangana, RBSE | Foundational chapter. Every board starts Class 8 Maths here. |
| Squares and Square Roots | CBSE, AP, Telangana | Core skill chapter. Prime factorisation and long division methods appear in both SA1 and annual papers. |

How to Use the 2018 Maths Paper for Exam Preparation
Step 1: Confirm Your Board and Download the Correct Paper
This is the single most important step. Download only the paper matching your board, state and medium. A CBSE paper and an AP SCERT paper test different chapters in different question formats and at different difficulty levels. Using the wrong paper creates inaccurate preparation and false confidence.
Step 2: Map Every Question to Its Chapter Before Solving
Read through the full paper and write the chapter name next to each question. Count how many questions or marks came from each chapter. This chapter-marks map tells you exactly where to focus revision time before the actual exam.
Step 3: Solve the Paper in One Sitting Under Timed Conditions
Set your timer to your board’s exact exam duration. Work through the paper in order. Show complete working for every numerical problem. Do not skip any question, even if unsure. Write whatever you know for partial marks where applicable.
Step 4: Self-Check Objective Sections Against Textbook
For MCQs and fill-in-the-blank questions, check your answers against the NCERT or SCERT textbook directly. This reinforces precise formula recall and definition memory better than passively reading a printed answer key.
Step 5: Compare Long Answer Working With the Answer Key
For 4-mark and 8-mark questions, compare your method with the expected solution in the answer key. Focus on whether each step was shown, whether units were included and whether intermediate results were labelled. These are the three main sources of step-mark loss in Maths papers.
Step 6: Build a Chapter-Error List and Target-Revise
After checking the full paper, list every chapter where you lost more than half the available marks. These are your priority revision targets. Revise those specific chapters using textbook exercises before solving another year’s paper.
Chapter-Specific Tips for the Highest-Marks Areas
Rational Numbers
- Learn all eight properties of rational numbers (closure, commutativity, associativity, identity, inverse, distributivity) with one example each. MCQ questions test knowledge of which property is used in a given operation.
- Practise representation of rational numbers on the number line. This appears as a 2-mark short answer in AP and Telangana papers.
- For numerical operations, always simplify to lowest terms before stating your final answer. Unsimplified answers lose 1 mark in most marking schemes.
Squares, Square Roots, Cubes and Cube Roots
- The prime factorisation method for square and cube roots is the most tested method in 2018 papers across all boards. Practise it with at least 10 different numbers until the grouping steps are automatic.
- For CBSE SA1 papers, the long division method for square roots is also tested. Know both methods.
- Identifying perfect squares and perfect cubes is an MCQ topic. Know the perfect squares up to 625 and perfect cubes up to 1000.
Comparing Quantities
- Word problems in this chapter follow consistent formats. Practise the five most common types: finding selling price from cost price and profit percentage, finding cost price from selling price and profit percentage, compound interest calculation, percentage increase and decrease, and ratio to percentage conversion.
- Always write the formula first, then substitute values, then calculate. This earns step marks even if the final arithmetic is wrong.
Mensuration
- Area and volume formulas are predictable. Write out all formulas for circle, rectangle, triangle, trapezium, cylinder, cone and sphere on one sheet and memorise them before the exam.
- The 2018 Kerala and CBSE SA2 Maths papers both had combined shape area problems. Practise splitting irregular shapes into standard shapes and calculating each area separately.
Linear Equations
- Every linear equation word problem has the same structure: define the unknown, write the equation, solve and verify. Practise this four-step method with at least eight different word problems.
- Verification step earns 1 mark in most board marking schemes. Always substitute your answer back into the original equation and write the verification line.
Mistakes Students Make With the 2018 Maths Paper
| Mistake 1 | Downloading the wrong board’s paper. CBSE and RBSE both test Rational Numbers but with completely different question formats and difficulty levels. AP SCERT and CBSE use different total marks and section structures. Always confirm your board before downloading. |
| Mistake 2 | Not showing step-by-step working in numerical answers. Every Maths paper in 2018 across all boards awarded step marks separately from the final answer. A correct answer without working earns partial or no marks. Show every calculation step. |
| Mistake 3 | Skipping the verification step in linear equation solutions. Most board marking schemes for 2018 Maths allocated 1 mark specifically for the verification step. This is a guaranteed mark that requires only 15 seconds to write. |
| Mistake 4 | Spending too much time on one difficult long answer question. In all 2018 Maths papers, long answer sections offered internal choice. Students who answered the difficult alternative when an easier option was available consistently lost time and marks. |
| Mistake 5 | Not practising cube root by prime factorisation before the exam. This chapter topic appeared in CBSE, AP, Telangana and RBSE 2018 papers. Students who had not practised the prime factorisation grouping steps made systematic errors that cost full marks. |
Preparation Checklist for 2018 8th Class Maths
- Confirm your board and download the correct 2018 paper (SA1, SA2 or annual) in your medium.
- Map each question in the paper to its chapter before attempting.
- Write all formulas for Mensuration, Algebra and Comparing Quantities on one sheet and memorise them.
- Practise prime factorisation for square roots and cube roots until the steps are automatic.
- Solve the full paper in one sitting with a timer set to your board’s exam duration.
- Self-check objective questions against your SCERT or NCERT textbook.
- Compare long answer working with the answer key and note every step where marks were lost.
- Build a chapter error list and revise only those chapters in your next study session.
- Reattempt the same weak questions without reference material to confirm the gap is closed.
- Solve a second paper (2017 or 2019) after revision to confirm overall improvement.
