As per the previous year exam analysis, the KCET 2026 exam might be of a moderate to difficult level. KCET questions will be based on the first and second-year PUC syllabus as determined by the Department of Pre-University Education of Karnataka State.
Candidates cannot skip Mathematics in the KCET exam. Mathematics is a mandatory subject in the KCET exam, and skipping it would disqualify candidates from the KCET examination.
Candidates looking to score good marks in the Karnataka CET exam are advised to solve the KCET previous year question papers and mock tests. Solving PYQs of KCET will enable candidates to get an idea about the KCET question paper pattern and the marking scheme.
NCERT best books are a good choice for candidates to start if they want to prepare for the KCET 2026 exam. Upon finishing the NCERT books, candidates can move ahead to the crucial KCET best books. Additionally, the KCET best books are another resource that candidates can use to study for the KCET exam.
The identical chapters and subjects from Classes 11 and 12 are covered by the questions in both KCET and JEE Main exams. However, in comparison to KCET, the questions in the JEE Main exam are more difficult.
In KCET Physics, chapters such as Gravitation, Motion in a Straight Line, Oscillations, and Thermodynamics each contribute approximately 7% to 8% of the exam paper.
NCERT is the most important source for entrance exam preparations. Following the NCERT books for KCET preparations helps candidates to develop the foundation of all the topics and chapters. Along with the NCERT books, candidates can also go through the KCET previous year question papers and mock tests for their preparations.
A candidate's score in the KCET exam carries a weightage of 50% in determining the final rank. The higher the marks, the better the rank will be. The marks candidates secured in their Class 12 board exams also play a role, with a weightage of 50%. So, performing well in both KCET and the boards is necessary.
Chapters with maximum weightage in KCET Physics are Gravitation, Oscillations, Motion in a Straight Line, and Thermodynamics since they carry 7% to 8% weightage. Important chapters for KCET Mathematics include Vectors, Integration, Permutation and Combination, and 3-D Geometry carrying a weightage of 6% to 7% in the KCET exam.
