Yes, you have a decent chance to get VIT-AP CDA (Computer Science with Data Analytics) because:

You're from SC Mala Category III, which usually has relaxation in closing ranks.

If last year’s closing rank was 29k and your rank is within a similar or better range, then considering your reserved category, you have good probability of getting a seat.

Still, it depends on this year’s competition, seat matrix, and your actual rank, so make sure you participate in all rounds and keep your options open.
