how to study chemistry and physics thoroughly in short period of time?and also biology?
Hello Pratiksha
I hope you are doing good
I would like to tell you that for stuyding core subjects like pcb you definately need a plenty amount of time. In short period of time try to cover easy topics which do have maximum weightage in exam and first step is to download the 10 year of all subjects . For chemistry follow the book pradeep and focus on easy topics like solid states,chemical kinetics and surface chemistry and for physics focus on chapter like electrostats,magnetic field ,optics . Be consistency and practise daily
Hope you found this answer helpful. Good luck for your future
