Is there any way to apply for additional credit hour from UTAR?

I was an exchange student for one sem under a UTAR program but originally I can still graduate in time. However, UTAR recently made changes & decreased their max credit hour to 20 hours in a long sem and because of this, I have to extend one long sem just to take ONE subject. The problem is that I must complete my studies in the original time period to qualify for PTPTN loan exemption.

I have only exceeded the max limit by 1 credit hour, can I apply for an additional credit hour?
