There is no syllabus per se for B.Sc PU CET entrance exam. You will be tested on your knowledge in Physics, Chemistry and Biology/Mathematics at 10+2 level. Each subject will have 60 questions. Every right answer gets you 2 marks and a wrong answer takes away 0.25 marks in the form of negative marking. So you have to prepare based on your 12th NCERT books. Unfortunately we couldn't get hold of previous papers for you. Sorry about that.
