Hi Ashok,

I understand that due to some misfortunate injury to your left hand you are not able to upload your left fingerprint or thumb impression of your left hand while filling up your application form for neet 2020 examination and thus you inquiring for the same as to what would be your further proceeding when you would be asked for your right hand thumb impression in the examination centre of neet 2020 examination and so to answer your question you need to first address the scenario to the competent authorities via post by clearly stating your health condition with supporting documents verifying the same and also request them for advising you on further proceeding for retaining your candidature for the examination you might also suggest them for considering you for uploading your right hand impression in place of your right hand impression as you are injured on the other hand and also request them for an expedited solution in this matter in which case would be asked to upload your right hand thumb print in the examination hall for candidate verification.

BEST WISHES!

dear ashok,

you don't need to worry about it because in neet bulletin it is clearly mentioned that

The candidate should put his/her left-hand thumb Impression on white paper with Blue Ink and scan for uploading. In case of any eventuality of left thumb being unavailable, right hand thumb impression may be used.

in the correction period if NTA provide in the correction of uploaded image then you can change your thumb impression otherwise you should give right thumb impression at the time of exam and counselling.
