I'm in 11th std and I'm preparing for JEE mains in 2019 I'm writing how can I make perfect timetable and how many hours should I sleep a day

Hi niketh . I am happy that you are planning to start you preparation for IIT. And it's a good time to start as you are in 11th. The timing and hours depends on your daily routine and interest. I was preparing for both engineering and medicine. I ll tell you what I personally feel good. If you make a entirely different schedule from what's being taught at school. It isn't going to help. I would advice you to try and make a schedule that would be in sync with your academic curriculum at school. So that you can dedicate time for both school exams and entrance efficiently. Even if you are dedicating a solid 1 hour with complete concentration. That's more than enough. But it depends on you. The way u read, your interests. An average of 1 to 2 hours with complete dedication is good enough. Listen to lectures in class , read the same topic in the evening , solve questions from that topic. Try solving as many as u can. The more u solve the merrier. But do remember to correct and analyse and rectify your mistakes. That's the vital part of learning. Not just solving. And after that you can take a break , relax and do your other homeworks too. Use your weekends to complete pending topics and revise whatever u learnt that week. The more u enforce a topic. It sticks better. Hope this helps.  Good luck

It's totally depends on you how's  you managing your daily routine .Make your timetable in this manner so that you can give your maximum time only on study.

Make sure you give at least 2hr/day on each sub... PCM
