Dear Charu;

This is a very important time so be careful and do not loose your confidence. Do not try any new concept/new book/new test at this time.revice only your old notes(coaching or yours notes).By this , you can revice full syllubus in a very short time and that will give you confidence. And most important do not try to check your rank at this moment.
