Hello aspirant, if you have paid the application fees then don't worry. Download the final acknowledgment form and the last page of the form contains details of fee paid such as transaction id , date etc. This is used as the proof of fee paid for the KCET 2021 exam. Keep at least 3 printout of final application form and proof of fee paid page along with 2-3 copies of photograph for future reference and counselling process.

BEST OF LUCK!!
