According to me class 10th marks doesn’t even matter and class 10th marksheet is just a proof of your DOB;)
I have seen many people who don’t have great result in class 10th but now they are studying in reputed medical colleges of the country.
For cracking NEET what matters is how much effort you put during the +1 & +2 or during the drop year. So even if you don’t have great result in class 10th you can still do wonders in NEET.
Thanks for reading and All the Best:)
