Hello Bhupen,

Since NTA requires you to upload the running hand signature of your full name as a proof of your identity while registering online for the NEET UG 2019, it is advised to you that since the correction window is open till tomorrow, you should re-upload the signature because it is likely that during exam when asked for your signature, if they don't match with the one uploaded by you, it may cause a problem, so its better to abide by the rules.

Hope this resolves your query, feel free to ask more.

Best wishes for your future.
