In Physics, building concepts is not a tougher job but building right concepts is much tougher.Whereas in case of Chemistry, just you need to put your efforts on PRACTICE in case of Inorganic Chemistry. In case of Organic part, just first build up your all basic Reactions, then start do practicing. And for Physical Part, same thing you have to do as in case of Organic Part. For Maths just use your brain as much as you can.
Go through some of the points:
1) Always start from basics and try to understand the subject don't mug up.
2) Never prefer solutions of questions before you do it yourself. Answer is not important but the way you proceed is more important for understanding concepts.
3) Always try a question with concepts, not just read the question then start doing without getting the point that what question is saying.
4) And be confident while you are preparing.
5) Take help of your teachers,seniors.
6) Its not necessary to study whole day but whatever time you spend while studying make use of it and concentrate fully.
