Hello

There is nothing called best timetable however here are some tips for you to study better. Get up early morning before sunrise and then start your routine work and after that start studying. Take 15 minutes break after every 60 minutes as we need a short break to increase our focus and concentration. The only mantra is 'Early to rise, Early bed', when you get up early and own your morning things turn out more beautiful and sleep well and on time. Have good food, keep dinner as light as possible. Do some sort of physical exercises in the day that will help you lower your stress and increase your concentration too.

All the best. Hope this answer helps.

Firstly set the goal that how much marks you want to score in your boards.For physics you should first learn all the derivative which are Important from examination point of view and then solve formula based numericals .In chemistry try to learn all the reactions and solve numericals in Physical chemistry.In maths practice questions as much as you can and revise all the the important formuals and concept again and again.for Hindi and english read all the stories and then try to answer questions in your own language.if you are able to give answers without grammartical mistakes then you. Can score good n Hindi and english

Devote approx 1 hour to each and every subject to reach upto best percentage and gain merit .

Thanks

All the very best
