To secure a free seat in an AI/DS (Artificial Intelligence and Data Science) engineering program through TS ECET in Hyderabad, candidates generally need to aim for a rank below 1000. However, this can vary based on the specific college and category (OC, BC, SC, ST). Candidates also need to fulfill the Telangana domicile and income criteria.

If a candidate doesn't meet the full fee reimbursement criteria, they might still be eligible for a partial fee reimbursement.

Hope it helps!
