Hi Mangesh,

The preparation for any entrance exam doesn't depend on how many hours you study. It depends on the way of preparation. The following tips will help you in that-

• Go through the syllabus and make a time table for each day you have left for the exam. Make sure you will get time for revision.
• You can start with studying the important books for CET.
• Then you can solve prvious year question paper with setting time.
• Go for the topics which have more weighatage and then for the other.
• Since there is no negative marking you can attempt almost all the questions if time permits.
• Practice more for the subjects which are little tough for you. It will help you in your score. 

Just be confident and dedicative. Hope this helps.

All the best!!
