Hey Manish,
This is a very big question, with no simple answer. It depends how much help you need. The further you are from your goal score, the more outside help you should seek out. Take a practice test (you can get a free one here on our website) and see where you are. If you're far off where you need to be, consider taking a class. If you're close, you can do it on your own with a good set of books!
