Hello,
At a neet score of 507 you have less chances at government institutions as the cut off is high but you can try at self finance college at kerala as the previous year cutoff was 481.
However as you know that cutoff changes every year depending on various factors like difficulty level of the exam questions , number of candidates appearing and the recent COVID19 crisis etc.
You can use careers360 college predictor to know the colleges you can get at your NEET score:- https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer
