Dear student,

First of all, you have not mentioned for which thing, like college/course you are preparing. So, without knowing that we are unable to help you. But if you tell us the course, so according to that we will tell you its qualifying examination. And, also only then we are able to tell the best possible way to crack it with good marks.

So please post a new question, with the course name you want to prepare. Only then we can help you.

Hope this helps.
