Hi guys, I just started to pay ptptn. I have a few questions here. Just curious about the ujrah thingy.

1. For example if my debt is 30k. The repayment time is 15 years. If I managed to finish paying the loan in 10 years, does that mean I will pay less for the interest, or the interest is fix even I finished paying earlier.

2. Let's say if I accidentally skipped one month payment, will I be charged for extra interest or principal cost? Even I repayed two months in the following month?

3. How do I know when is the date that is the deadline for me to pay every month? Will ptptn send me an email? I worry I miss the deadline and get charged for extra cost.

Thanks for answering.
