With a rank of 81,245 in EAMCET (assuming this is AP or TS EAMCET) under the SC category, your chances for a seat in top-tier colleges like

• JNTU (Jawaharlal Nehru Technological University) or
• CBIT (Chaitanya Bharathi Institute of Technology)

are very slim for popular branches like CSE, ECE, or IT, because these institutes have very high demand and their closing ranks for SC category are usually much lower (within 40–50k or even better). However, you might still have a chance in less competitive branches like Mechanical, Civil, or Biotechnology in some of their affiliated or constituent colleges, depending on vacancies and the specific counselling round. You should also keep your options open for other good colleges where your category reservation might help secure a decent branch. Apply in multiple counselling rounds, and also check for spot admissions in private institutions — sometimes good colleges have vacancies in later rounds for specific categories.

Thank you!
