Dr. Farrah, Are doing MCQs? If the answer is YES, then are reading the explanatin with full concentration? If YES, are adding some new points on the original material you have read? If the answer is yes, then go through your notes again, and keep doing MCQs. Remeber to give one hour for the HY at least every day. Make fix, every day, one more hour for another HY material you have chosen to do. Do every day 50 question with the explanation, all of it, the wrong and the correct ones.

Good luck Smile)
