Hey, Pallavi!
Considering that you're a PCM student and you just have 10 days in hand, it is advised that you should go through the previous year question papers and try solving that. If you can manage to take out some time and go through the material given in NCERT textbooks, topics related to genetics, biotechnology, reproduction and reproductive health, ecology and environment should be given attention to. Hope that it helps. All the best!
