Cramming has always been a negative factor for students which seems easy to them but in reality, it is not. Cramming part provides you with an illusion that yes, you have learned everything but the reality differs from what it seems. The entrance examinations to get into the best engineering colleges require the understanding of concepts, and not cramming. You need to understand each and everything as the questions in the entrance examinations are not like junior high school question papers where you will get direct questions related to what is in the prescribed books. The question will be based on the concept but not what you will expect, i.e., tricky. To solve these questions, you need to have a deep understanding of the topic so that you can solve questions easily.
