Hi student!
Yes, with a score of 252 in NEET and belonging to the SC category, you have qualified the exam. However, getting a seat in a government medical college for MBBS is quite difficult at this score, since SC category cutoffs for government colleges through both AIQ and state quota usually range much higher, often around 420 or above.
Still, you may have a chance in certain private medical colleges, especially those that offer government quota seats. Some states like Tamil Nadu, Karnataka, Uttar Pradesh, and Maharashtra tend to have lower cutoffs for SC category candidates in the later rounds of counselling, including mop-up and stray vacancy rounds.
