Hello aspirant , it depends on the reason . Why you got this score , if you were not prepared , did not take proper coaching and followed a routine then it is different case. If you have tried , you studied and still couldn't make it , it is a different thing . If you did not study for this attempt in a proper way , then you give another try , else don't . Moreover you should be ready to study for 10 - 12 hours everyday up gill NEET  . If you are ready go put that hard work only then you should take drop.
