By cracking I am assuming a decent rank. The level of CET examn is not that much high, so you can easily score good marks.
Firstly, go through the paper pattern. Just stick to the syllabus don't go beyond it. Study NCERT to build your concepts.
Maths: Have command on each and every topic. If you feel some difficulty in any topic, just have basic clear about that topic. You need to do a lot of practice for speed and accuracy.
Physics: Have command on every topic and most imporatntly, learn each and every formula by heart. Because there are questions on direct formula.
Chemistry: Read NCERT line by line, thats the success mantra. Practice organic chemistry.
The must to do thing, make short notes and revise them regularly. Do a lot of practice of previous year papers and give mock test to increase speed and devote time to analyse them.
During exam: There will be some time consuming questions , do not give a try to them. As there will be negative marking so attempt only those questions that are known to you. Attempt chemistry portion first as it take less time. Above all, be confident and don't panic in examination.
Best of Luck!!
if you have studied well for your 10+2 course have prepared for jee main this will not be a very big obstacle to crack. how ever you need to have a very good basic concept of physics, chemistry, math, biology as questions will be from all this subjects. exam will be in offline mood and you get 2 hr and 30 min for answer. revise the previous year question paper and work on your weak areas. practice a lot of mock test and learn a lot about time management. hope it helps.
Refer the link to get detailed information of the exam and its factors :
Solve mocks as much as possible and try to solve Qs in time bound manner.
It is relatively easy than jee.Study 11th and 12th textbooks thoroughly.
Hope I helped you.All the best for future endeavour!!
