I can't definitively say whether you will get a free MBBS seat in Telangana for 2024 with a score of 435.
The cutoff for SC category in Telangana for NEET 2024 admissions isn't available yet. The official authority, Kaloji Narayana Rao University of Health Sciences (KNRUHS), will release the cutoffs after the counselling process

As of June 2024, the Hyderabad High Court has directed the Telangana government not to admit students under the sports quota for MBBS admissions this year.

Keep an eye out for official announcements from KNRUHS regarding the NEET 2024 cutoffs and counselling schedule
