Retaking subjects depend on how your university calculates CGPA. Some schools practice "append method", where the amount of pointers you get is divided with the total credits you've attempted. This means the more time you repeat, the harder for you to score.

Other schools use "replace method", where your pointers is divided with the total credits acquired. This means you can repeat and replace old grades as you wish and the only drawback is time.

There are several issues with your intent:

1. If I'm not mistaken, PTPTN only consider 1st class with graduate on time for the exemption. Please check on this. If confirmed, it means you have to retake 4 subjects without adding a semester to qualify.

2. Most schools take the latest grade. Meaning if you repeat a C+ subject, but get a C later on, you will use the C and the C+ is burn.

3. Some schools don't even allow retaking a non-failed subjects. And those that do, have an upper limit. Meaning you can only repeat C+ subjects, but not B-.

For UTM, foundation and all UG irrespective of faculties will use the same method? And which one?

I don't know about foundation, but for UG, we use the replace method.

Previously I did my diploma and doing my degree now.

So, I did Credit Exemption for 5 subjects which is around 1 semester. Means I got 1 semester extra left I can use to retake the 4 subject without extending. Will it work? What do you think?

In case of needing a few more points to obtain first class degree, is it possible to write an appeal letter to dean/chancellor to allow special exemption to this rule?
Per your experience, has there been a case of this in the past?

For schools that follow the no-retaking of passed subjects, I believe the answer is no. Exemption means they are reversing a position that they have set from the beginning. I find it very unlikely that they would do that.
