i was not able to concentrate

Hi sunilparthan, first of all, find out what is really disturbing your mind? If you have a personal problem, you need to solve it so that it will not continue to bug you when you study. There are other reasons that might cause you to lose concentration: 1. exhaustion 2. environment 3. health (flu, headache etc.) 4. anxiety (worried of exam, worried about family members who are ill etc.) When you have either one (or more) of these reasons, you should not force yourself to study. Go out; hand out with friends, watch TV, call up your buddies etc. If it's an environment problem, go to another location to study. Hope this helps, and good luck
