Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

For Cell Biology portion it would be better you follow Albert's Cell Biology Book. It has more illustrative examples, Practicals & Experiments The diagrams in the Book are well defined. If you go throughly through it would be boost your prepartation. But there would be a lot of information & so much of knowledge. So I would suggest you that you stick to the syllabus & Study should be focussed well from exam point of View. You should restrict yourself from diverting a lot from the exam syllabus & studying all the details given in it. Best of Luck.
