With a JEE Mains rank around 65,000, you have a good chance to get admission in decent government and private engineering colleges for ECE (Electronics and Communication Engineering) and CSE (Computer Science Engineering). While top IITs and NITs may be difficult to secure, you can consider some of the newer or state-level NITs, IIITs, or reputed private universities like VIT, Manipal, or Amity, which offer strong programs in these branches. It's important to check the opening and closing ranks for the current year, as they vary each year. Also, exploring state quota seats and private universities with good placement records can be a practical approach to secure a quality education in ECE or CSE.
