Hi Nikita!

Exam will consists of the two parts: Part A will have questions of 10+2 level from Physics, Chemistry, Mathematics and Biology.  And part B  will have basic questions of graduation level from Biology, Life Sciences, Biotechnology and allied areas. For part A, I will suggest you to go through the NCERT books thoroughly. Along with this you can prepare Physics from HC Verma, Maths from RD Sharma, Chemistry from OP Tandon, Objective Biology by Dinesh.  For part B, you can use the books which you used in undergraduation degree. Some other books you can follow- Biotechnology by Saras Publications, A Textbook of Biotechnology by R C dubey etc.
