Hiii

All you need is the dedication and honesty towards your work and study.
First things first for the next 4 months in your hand try to cover all the important topics. Do not waste time unnecessarily studying anything and everything coming your way
Try to clear all your concepts and have a clear vision about any topic you have covered.
Don’t stress out, just keep up the good work with all your dedication and desire to get through it.
Firstly make a schedule of your daily routine and fix 8-10 hours of study with maximum possible efficiency.
Sleep efficiently and wakeup early and revise all the your topics covered yesterday, its one of the best practices to do.
Smart study is something which you need to practice at this point of time.
There’s no need of studying continuously, divide your day in slots of 3-3 hours  with breaks in-between. So that both your body and mind remains relaxed and ofcourse efficient.
Practice Practice and Practice!!!
Note down all the formulas and important concepts so that they become handy for revision.
Don’t let your doubts pile up. Talk to your teachers they will be more than happy to help always and of course internet is always there. You can also post your questions on careers360 so that we can help you.
Always revise in your mind before sleeping as it would help you in remembring things more efficiently.
And also, 
Take online mock tests. 
Improve your calculation speed.
Try to solve sample papers and previous year papers regularly and time all your papers so as to analyse your speed and result.
Focus on tricks to solve your questions rather than wasting time on lengthy calculations.
Create exam hall like situation when you are solving your papers and remove all the disturbance. Keep a water bottle with you so that you are not getting disturbed.
Don’t get demotivated if your score is less in earlier attempts as it would automatically gain a pace with time.
Also I won’t advice you for late night studies, Sleep Early so as to keep your mind active and fresh.
And the most important advice don’t let anyone or anything break your flow, forget all the occasions for these 4 months.
