The HSC is very stressing as everyone keeps on reminding you….. Here is a tip which helps you to understand what you have studied in a better way.
On the first day, you study what you learned in class. Then you read and study about 2 pages of your text book ahead, but just briefly, so you have the preview of what it is about. The next day in class, the teacher will teach the method, and you already know the basis of it, so it all clicks you in understanding the concept clearly.
