Hey I was a brilliant student .now my studies is going wrong completely.me really afraid of my future please help me any... I can't concentrate my mind gets diverted... so.

Hi Shobraj,
May I know how old are you? And what are the distractions that you face?

The best time to study is when your mind is relaxed and there are very few distractions, like early morning hours or late night.

Also, are you losing interest in your studies? If so, why not try to study with a friend(make sure he/she is into studying and is sincere, you wouldn't want further distractions.).

Are you finding any of your subjects difficult? Ask your teacher or a friend/senior to help you out with that subject.

And take short breaks after each hour of studies.
