Hi,

Well you won't usually find CUET specific books for practice for all different subjects. It would be good if you can have books on your concerned subject, like a workbook that has MCQ type questions and then all you need to do is practice them. The pattern of exam is just like any other exam and you won't have to stress yourself too much for the questions. A good preparation of the subject basic information will let you clear the exam quite well. Focus on clearing the basics and subject specific knowledge.

I hope this helps.

All the best.
