I am very weak in hindi. In acadmics I can only score 70 to 80 marks despite of the hard work. I want to score 95 plus marks. Tell me what shoud I do. I will definitely follow your advice.

U must read. The concept which you find easy and u must understand the summary and try to write in your own manner for a few times slowly u will get full confidence. And read the lesson thoroughly. And understand in your mother tongue. That's all my friend
