There is a reason students keep searching for the 2018 Maths question paper years after that exam was written. It is not about nostalgia.
Class 8 Maths is the foundation layer for everything that comes next. Algebra, geometry, rational numbers, exponents and powers, mensuration, linear equations. These chapters do not disappear after Class 8. They come back harder in Classes 9 and 10. A student who gets comfortable with the 2018 paper is quietly building skills that pay off two years later.
The 2018 papers also reflect the exact question style and difficulty level of current exams for Telangana, AP, RBSE, and Kerala boards, since the syllabuses for Class 8 Maths have not changed significantly since then. This makes the 2018 paper genuinely useful, not just historically interesting.

How to Use the 2018 Maths Question Paper to Actually Improve
Most students download the paper and do one of two things. They either read through it without solving anything, or they solve a few questions and then get distracted. Neither approach works. Here is what actually produces results.
Step 1: Identify Your Board and Paper Format First
Before you touch the 2018 paper, confirm you have the right one. A Telangana student needs the TSBIE SA1 or SA2 paper. A Rajasthan student needs the RBSE board paper. A CBSE student needs a school-level or KV sample paper. Using the wrong board paper gives you the wrong chapter coverage and wastes revision time.
Step 2: Sort Questions by Chapter Before You Attempt
Go through the paper and write down which chapter each question comes from. This creates a chapter-wise map of what is being tested. You will immediately see which chapters carry the most questions and which ones are tested lightly. Prioritize your revision based on this map.
Step 3: Attempt the Full Paper in One Sitting
Set a timer for the full exam duration (2.5 to 3 hours depending on your board). Attempt every question. For Maths, never skip a question completely because partial marks are available in most boards for showing correct working steps even when the final answer is wrong.
Step 4: Mark Your Own Paper Using the Answer Key
This step is where students grow the most. Compare your working method against the answer key, not just your final answer. Pay attention to how the answer key sets out each step. If your method is different but correct, that is fine. If your method is wrong but your answer coincidentally matches, you will lose marks in the actual exam because the examiner checks steps.
Step 5: Create a Formula and Error Log
After marking your paper, write down every formula you used incorrectly and every concept you got confused about. This is your personal revision list. Review this list two days before your actual exam. It will contain exactly the things your brain needs reinforcing.
Topic-Wise Preparation Guide for Class 8 Maths 2018 Papers
Rational Numbers
This chapter appears as 1 to 3 questions in almost every 2018 paper across all boards. The questions test properties of rational numbers (closure, commutativity, associativity) and operations. The most common mistake students make is confusing the rules for adding fractions with unlike denominators and applying the wrong sign when dealing with negative rational numbers.
- Practice at least 10 addition and subtraction problems with negative rational numbers
- Memorize the four properties for both addition and multiplication: closure, commutative, associative, distributive
- Learn to represent rational numbers on a number line as this appears as a 2-mark question
Linear Equations in One Variable
This is the highest-scoring chapter in almost every Class 8 Maths paper. Word problems from this chapter carry 4 to 6 marks in RBSE and CBSE papers. The 2018 papers consistently tested the ability to convert real-world problems into equations and solve them.
- Master the technique of transposing terms from one side to the other
- Practice word problems involving ages, speeds, and quantities as these are the most common formats
- Check your answer by substituting it back into the original equation before writing your final answer
Comparing Quantities
Compound interest is the most frequently tested topic from this chapter. The 2018 papers across all boards included at least one compound interest problem. The formula A = P(1 + r/100) to the power n must be memorized correctly.
- Know all three compound interest formulas: amount, compound interest, and effective rate
- Practice the percentage increase and decrease formula: new value minus old value divided by old value multiplied by 100
- GST problems appeared in 2018 papers for the first time across several boards as GST was introduced in India in July 2017
Algebraic Expressions and Identities
The four standard algebraic identities are the core of this chapter and are tested in every 2018 paper. Memorize these exactly:
- (a + b) squared = a squared + 2ab + b squared
- (a minus b) squared = a squared minus 2ab + b squared
- (a + b)(a minus b) = a squared minus b squared
- (x + a)(x + b) = x squared + (a + b)x + ab
Questions ask you to expand expressions, simplify them, or use identities to find values like (99 multiplied by 101) without long multiplication.
Mensuration
Mensuration in Class 8 covers area of plane figures and surface area and volume of solid shapes. The 2018 papers tested trapezium area, area of quadrilaterals using diagonals, and surface area of cubes and cuboids. Kerala’s 2018 paper placed heavy emphasis on this chapter with multi-step geometry problems.
- Learn the trapezium area formula: half the sum of parallel sides multiplied by height
- Learn the area of a rhombus using diagonals: half multiplied by diagonal 1 multiplied by diagonal 2
- Surface area of a cuboid: 2(lb + bh + lh), Volume: l multiplied by b multiplied by h
- Surface area of a cube: 6 multiplied by side squared, Volume: side cubed

Formula Quick Reference: Most Tested in 8th Class Maths 2018
| Chapter | Key Formula or Rule | Paper Frequency |
| Rational Numbers | Additive inverse of a/b is -a/b, Multiplicative inverse is b/a | Every paper |
| Linear Equations | Transpose and solve: ax + b = c gives x = (c – b) / a | Every paper |
| Squares and Square Roots | Square root by long division method; (a+b)^2 = a^2 + 2ab + b^2 | Most papers |
| Cubes and Cube Roots | Cube root by prime factorization; perfect cube check by grouping factors in 3s | Most papers |
| Comparing Quantities | A = P(1 + r/100)^n for compound interest; SI = PRT/100 | Every paper |
| Algebraic Identities | 4 standard identities; (a+b)^2, (a-b)^2, (a+b)(a-b), (x+a)(x+b) | Every paper |
| Mensuration | Trapezium area = 1/2 x h x (a+b); Cuboid SA = 2(lb+bh+lh) | Every paper |
| Exponents and Powers | a^m x a^n = a^(m+n); (a^m)^n = a^(mn); a^0 = 1 for any non-zero a | Most papers |
| Factorisation | a^2 – b^2 = (a+b)(a-b); a^2 + 2ab + b^2 = (a+b)^2 | Most papers |
| Data Handling | Mean = sum of observations / number of observations; Probability = favourable / total | Most papers |
Common Mistakes in Class 8 Maths Exams and How to Avoid Them
- Forgetting to write units in mensuration answers. Area answers need square units (cm squared, m squared) and volume answers need cubic units. Examiners deduct marks for missing units.
- Applying simple interest formula when compound interest is asked. Read each question word for word before choosing your formula.
- Sign errors in algebra. When transposing a term, the sign always flips. Plus becomes minus, minus becomes plus. This single error causes the most avoidable lost marks.
- Writing the identity incorrectly. Many students write (a + b) squared as a squared plus b squared, missing the 2ab term. Write out identities three times from memory before the exam.
- Skipping prime factorization steps in cube root problems. Show every step. Partial marks are given for correct working even if the final grouping is wrong.
- Not checking divisibility when factorizing polynomials. Always verify your answer by multiplying the factors back out.
- Spending too long on a single difficult question. In a 3-hour exam, allocate roughly 2 minutes per mark. A 4-mark question should not take more than 8 to 10 minutes.
