Hello, 

Even with a reservation quota of SC category your score of 150 marks is a low score. Chances of admission in MBBS/BDS courses with this score is very less. You can try for admission in Management Quota but that will require alot of fee and donation. 

You can take a break of one year and prepare for NEET 2020 with proper dedication and confidence. Or you can change your field and do other graduation courses.

Hope this helps.

Good Luck.
