Physics is a deep and interesting subject that requires your continuous attention. If the theories could be the horse that would pull the cart of problems and MCQs, always put the horse before the cart, and never the other way around.

Don’t learn the theories by rote, or cram some dry formulas without context. Understand how a theory evolves, a physical quantity is defined, a formula is derived, a physical law or principle applies to solve problems.

Do not leave grey areas where a concept or a derivation confuses you; clarify them with a good teacher. Trust me, if you understand the theories well, you are almost equipped with the technique and confidence to crack numerical problems and MCQs.

So, as you finish a topic/subtopic within a chapter, attempt simple, straightforward problems based on it. If you can’t solve one, see the hint and try again. This way, as you finish a chapter, you already have solved a number of entry-level problems. And – voila – solving these problems, in turn, firms your grip on the theory and boosts your confidence! That is your BASIC-LEVEL PREPARATION.

Now, you will attempt more challenging problems based on a single topic or a combination of topics done in the chapter. Sometimes, the solution may require additional inputs from topics done in other chapters. How helpful it would be if somebody could grade the problems, authentically, as follows: “least challenging”, “moderately challenging” and “most challenging”! Because that would jerk you up to the right spirit as you sit with pen and paper.
