Hiii
First things first, you must be dedicated towards you study.
Since now only 5 months are left for the exam you need smart study at this point of time. Do not waste time unnecessarily , analyse your strong ans week parts. Revise all the topics that you feel you have strong hold on so that you do not need to waste time on them again and again.
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. 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.
Sleep efficiently and wakeup early and revise all the your topics covered yesterday, its one of the best practices to do.
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, Remember to give equal time to all the three subjects physics chemistry and biology. Do not leave any of the three subjects. Find out which topics get more weightage and try to focus more on them. Here is a link for the same: https://medicine.careers360.com/articles/neet-chapter-wise-weightage-and-important-topics
Take online mock tests to Improve your 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.
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. Also engage in some physical exercise like a short evening walk so that you remain active.
And the most important advice don’t let anyone or anything break your flow, forget all the occasions for these 5 months and focus only on your goal.

Thanks!
