With a TS EAMCET rank of 30,000 from Andhra Pradesh, you have a good chance of securing a seat in several engineering branches, though CSE and high-demand branches may be difficult. You can likely get seats in branches like Mechanical, Civil, Electrical, or related fields in mid-tier or newer colleges. The availability will depend on the cutoff and category reservations. It's best to explore colleges outside major cities or those with lower cutoffs to improve your chances of getting a seat.
