I assume you are asking about COMEDK UGET FOR ENGINEERING.
- Physics: The paper will be easy with 60 questions. Time management and accuracy is a must. If you are clear with your concepts you will easily get 50+. Past year papers will be the best to prepare for it.
- Chemistry: The paper will be damn easy. Studying NCERT is more than enough. The chemistry paper should be completed as fast as possible because you need to give more time to maths. One can easily get 50 on 60.
- Maths: The maths portion is usually lengthy. Its time taking. One should effectively manage time in this portion. According to my opinion its difficult compared to physics and chemistry. Keep this section at the end if you think you are not very fast with your calculations. A score of 45+ can be considered good. Go through Past year papers.
One can easily cross the 100 mark. But that is not sufficient.
But if you want to be in top 1000, usually a score of 130/180 is mandatory. Plan accordingly and crack it!
