“If A Door is Closed, Doesn’t Mean It is locked”. You just have to push it harder. There will be times when you will not be able to open it, But you have to try it again and again.
Same is the case, when you start learning PHYSICS. but the one thing that you have to keep in to your mind is “Emphasize more on learning the concepts rather than cramming” and soon you’ll be rocking like a Pro.
You need to stay very focused and motivated to qualify the various competitive exams like IIT – JEE, NEET and IIT – JAM etc. So, don’t get disheartened when you are not able to solve the problems in the first go. “Just Keep on Trying Again and Again”.
