1- Numerical problems of physics are not the same as the problems in the mathematics. So do not try to memorise only the formulas and equations without understanding the concepts of the topic related to the problems.
2- Try to picture that have been said in the numerical problems. So read the problem carefully and don’t try to read like you are running out of time.
3- You must start to solve numerical problems with very easy, formula based, and “very short type” or “short type answer” questions. It will help you to learn the formula and basic concepts used in the problem and it will make you more enthusiastic towards problem-solving and strategy-making person for all physics problems.
4- You should never underestimate the Very Short Answer or Short Answer type questions because these questions are like learning key-board before you start to play piano.
5- For bigger problems try to draw a diagram with what have been given in the question.
6- Write down what you know and what you are trying to find out. In simple problems you may just do it in your mind but for more difficult problems it is very useful wherever you have to find out two, three or more results.
