Question

can anyone tell me how to score good marks in physics, chemistry and biology?? should we do inside or back ques ans ??

Answer 1

read each and every line in your text books. you can draw tabular columns or flow charts for understanding.

Answer 2

I have a good idea. Just take a portion that you wants to study today and take a special notebook for it. Then write all the one words and questions u getting from there to the notes. Just tell this same idea to your friends, maybe anyone will be interested. When u are studying together u will have an interest in studies
This is how me and my friend studies. They ask me that we need a timetable to study because all of us got lesser mark in the last exam so we started this way. Just try it.
