Hi

As per your rank 20533, only if you have a State Quota then you may hope to get a seat in Coimbatore Campus. As per previous year closing ranks were: Aerospace Engineering-19892, Civil Engineering-19971, Chemical Engineering-19678, Electrical & Electronics Engineering-19433 and Electronics & Instrumentation Engineering-19822. So you can consider these choices in Coimbatore.

All the best.

Hope this helps.
