Hi !!

Actually the main thing is consistency , if you are studying 2 hrs each subject (physics,chem,bio) each day then nothing is better (then that will be more than enough ) than that but if you study one day 10 - 12  hrs and skips other two then no use of that..

Consistency and dedication towards your goal will definitely help you to achieve success / your goal .. I hope it helps ..Thank You..

Hello student ,

As you are a student of PCB so I think you might be good in biology so you should give your more time on Physics and Chemistry . Giving equal time to all the three subjects will be not enough because there a lot of students who sometime has problem in chemistry and sometime in physics . So I will suggest you to give 2 hours for physics , 2 hours for chemistry and 1 hours for biology .

Beside this include 1 hour in all the three for the revision whatever you have studied throughout the whole day .

Hope it will help you !
