Ques. Why does CUET Biology require higher marks than Physics for the same percentile?
Ans. CUET Biology is a factual recall subject with high NCERT alignment which leads to a higher density of high scoring candidates. Since percentile is relative, more candidates scoring 200+ means the same raw marks translate to a lower percentile in Biology compared to Physics, where fewer candidates clear the 200 mark.

How to Maximise CUET 2026 Science Stream Percentile
To get maximum CUET 2026 Science percentile, candidates should focus on NCERT revision, regular mock test practice, and balanced preparation across all science subjects during the final preparation phase.
- Class 12 NCERT textbooks remain the most important source for CUET Science preparation with 80% or more questions based on NCERT concepts.
- For Physics, numerical practice, formula application, and calculation accuracy remain important because small mistakes can reduce percentile significantly.
- In Chemistry, Organic Chemistry reactions, mechanisms, and NCERT based Inorganic Chemistry diagrams are considered important scoring areas.
- Biology preparation should focus on line-by-line NCERT revision because many CUET Biology questions are directly theory based.
- Candidates should attempt at least 5 or more subject wise mock tests per subject during the final week before the examination.
- Avoiding blind guesses is important in CUET because repeated negative marking can quickly reduce the overall percentile and aggregate score.

Ques. Are CUET 2026 science subject percentiles calculated separately?
Ans. Yes, CUET 2026 calculates the percentile separately for each subject based on the candidate's session and shift. This is why the same raw mark in Physics and Biology yields different percentiles. Universities then use the aggregate normalised score across selected subjects for admission rankings.
Ques. Can CUET science scorecard be used for engineering admissions?
Ans. CUET 2026 scores are not accepted by NITs and IITs for engineering admissions because those require JEE Main and JEE Advanced. However several CUET participating universities like BHU, DU, JMI, and AMU accept CUET science scores for B.Tech, B.Sc Hons and integrated science programs.
CUET Science Stream 2026: Reddit Discussion
- Reddit user u/LostVirus7003 asked for guidance on preparing for CUET 2026 from the science stream, mentioning that they are a dropper and unsure where to study theory from despite already purchasing a practice platform.
