Hiii

Its possible if you give all your efforts. All you need is the dedication and honesty towards your work and study.
Try to cover all the important topics. Do not waste time unnecessarily 
Try to clear all your concepts and have a clear vision about any topic you have covered.
Make a schedule of your daily routine and fix 8-10 hours of study with maximum possible efficiency.

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.

And also, 
Take online mock tests. 
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.

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 some time.

And Always remember hard and continuous work done with dedication never fails.

Good Luck!!
Thanks!!
