Hello Vidyuta,  everyone says that nothing is impossible,  I think this is right.  For neet 2020 you have 7-8 months in your hand so you will have enough time to study. So if you are passionate about your career and ready for smart work,  then you can score 600+ marks in NEET 2020. Don't see the current marks. If you have confidence in your studies then go ahead and start studying form now to achieve your goal.  

I hope it will help you more. 

Thanks.
