hello aspirant, 

CET is not the most difficult exams like JEE. YOu can crack it easily. ALl you need is a little focus and less mug up strategy. You should never byheart, UNderstand the questions and use your own short cut methods . With your own short cut methods and a little bit of focus on what is necessary and what is unnecessary in the given question can help you fetch more marks. 

Good Luck!
