With 72.73% in JEE Mains, OBC-NCL category, and Rajasthan home state, getting CSE in RTU Kota or CTAE Udaipur is difficult, but you may get other branches like Mechanical, Civil, or Electrical in later rounds. Both are top government colleges, so cutoffs for CSE are usually high. You should definitely apply through REAP Rajasthan counseling and fill maximum choices. Keep checking cutoff trends and be ready with documents. There's a fair chance of getting a decent branch.
