Hello,
Since you haven't completed the phase-2 registration for NEET 2021, your result of NEET 2021 will not be declared as mentioned in information bulletin by National Testing Agency NTA.
If you wish to appear again for NEET 2022, then leaving the phase-2 registration will not have any impact on your future examination. You can fill the form for NEET 2022 whenever it is out and can appear for the Examination.
Thank you.
