Frequently Asked Questions

1.How many questions are in the KCET 2018 paper?

This paper has 180 questions in total - 60 each from Chemistry, Mathematics, and Physics.

2.Can I practise questions from just one subject?

Yes. Use the Chemistry, Mathematics, and Physics tabs at the top of the page to jump directly to that subject's question set within this paper.

3.What is the structure of the KCET 2018 paper?

The KCET 2018 paper on MARKS has 180 questions, organised by subject:

  • Chemistry: 60 questions - 60 single-correct.
  • Mathematics: 60 questions - 60 single-correct.
  • Physics: 60 questions - 60 single-correct.
4.What is the difficulty level of the KCET 2018 paper?

Each question on MARKS carries a difficulty rating. Of the 180 rated questions in this paper, 94 (52%) are easy, 60 (33%) are medium and 26 (14%) are hard. Subject wise:

  • Chemistry: 32 easy, 20 medium, 8 hard
  • Mathematics: 31 easy, 20 medium, 9 hard
  • Physics: 31 easy, 20 medium, 9 hard
5.Which chapters had the most questions in the KCET 2018 paper?

The chapters with the most questions in each subject were:

  • Chemistry: Hydrocarbons (5), Alcohols Phenols and Ethers (4), and d and f Block Elements (4).
  • Mathematics: Probability (6), Application of Derivatives (4), and Determinants (4).
  • Physics: Current Electricity (6), Alternating Current (5), and Electrostatics (4).
6.Where can I find the solutions for the KCET 2018 paper?

Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole paper is coming soon.

7.How should I use the KCET 2018 paper to check my preparation?

Set a timer, attempt the 180 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for KCET. Repeating this with other papers shows whether the same weak spots keep coming back.

8.Will the KCET 2018 paper help me prepare for KCET 2027?

Yes. Every past paper shows the question styles and topics KCET has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
