Considering that you have the whole day in your hand a better approach than this could be if you study every subject every day.

Considering 6 hours sleep, and 5.5 hours for other things, you have 24–6–5.5 = 12.5 hours.

12.5 hours means you can dedicate 2.5 hours per subject. That would be an efficient approach since you are updated with all subjects.

If you are ready for this, you can easily achieve 90 above.

Always remember that 11th is very crucial for your future. Even if you don’t get good marks, don’t be upset. Its all about concepts. Please make sure each and every concept is clear in your mind. Study for knowledge, with knowledge good marks will also come.

Hello Mehras,

Relax You have alot of time left and you can easily cover starting from 0. You just need to do smartwork not the hardwork. See for chemistry i would like to prefer you Pradeep and nothing else in case you find NCERT boring. Pradeep has numericals on every Formula and is well explained, one thorough reading and chapter is done. The organic reactions just for quick revise, all of them are given at last pages of Pradeep and are well divided in categories. So your pradeep problem is solved.

For physics i would like to suggest SL arora. It has alot of numericals on every formula and concepts are made clear in very well manner. The seems interesting and not boring, and it also has NCERT exercise solutions so you should do that too.

Everything solved. These two books will make your way alot easier.

Hope this helps

Hey,
First off,stop worrying so much. You still have three months left with yourself. You can make atleast something out of this time.
See,three months is more than enough to cover your NCERT. Make sure you are done with your NCERT at the end of these three months. For Chemistry,NCERT is enough. Read and understand it. Solve the questions given in the book. For Biology also,NCERT is enough to a certain extent. For Physics,you can refer to Pradeep or Dinesh. Solve previous year questions. Talk to your teachers and ask them what all topics are more important with examination point of view. And keep faith in yourself. Put in your hardwork but do not stress yourself out.
Hope this helps.
Good luck.
