Hi Vijay,

As you have got the preparatory course you are well confused to take it or not. According to me, the very first thing you should see that you are satisfied with this course or not. If you are satisfied then you must take this opportunity but if you are not satisfied and thinking of compromising just for the sake of time then don't do this. I will suggest you to give another try if you are confident enough that you will get better than this the next time.
