Dear Anjali, you haven't mentioned the entrance examination you are enquiring about. If this is about GATE, October 5th was the last date to complete the application form, make the payment with late fees. However if you missed on making the payment yesterday, you cannot make it today because the deadline has passed. Now the payment will go through but the application will not be processed because the payment did not come in within the due time and the application fees will not be refunded either.
