How does your school calculate GPA?

I was just curious how your schools calculated weighted GPA? Unweighted is pretty self-explanatory, minus the fact that some schools consider an A+ to be a 4.33.
My school calculates weighted GPA in this extremely unusual way by adding the weighted points after calculating the unweighted. For example, if you had a 3.8 unweighted and had 2 honors credits (weight of 0.096), your weighted GPA would be 3.992. It makes it incredibly easy for anyone taking honors or AP to have an outrageously high GPA. I don’t like this system because it essentially rewards the highest class ranks to whoever took the most honors and AP classes. I know weighted GPA rewards these hard classes but it doesn’t seem normal for it to be possible for students to have an 8.0 weighted GPA senior year.
Does anyone else’s school do it this way or are your schools more traditional?

My school didn’t weight grades. They just used a typical unweighted 4.0 scale without pluses/minuses.

Weighted considers honors/AP as 5.0. However, the school only weights 6 classes and if you take additional ones they don’t count as weighted.

AP classes get an extra quality point for GPA, and most honors classes get an extra .5.

At my school we have that for a A, regular classes are 4.0, honors are 5.0, and AP are 6.0.

This is a bit of a frustrating topic for my daughter. Her freshman and sophomore years her HS used a 7 point grading scale (so an A was 93-100). Her junior year they switch to a 10 point scale (with 90-100 receiving an A). Of course her first two years she scored several 92%. We are able to make schools aware and if they recalculate GPA’s this isn’t a problem but for many public universities they only look st the GPA reported on the transcript. Just another wrinkle in the topic of GPA’s!

Here at my school AP courses were considered 5.0 and honors courses were weighted as 4.5

our high school has standard, college prep, honors, and AP/dual enrollement
A+ 98-100 3.8 4.3 4.8 5.3
A 93-97 3.5 4.0 4.5 5.0
A- 90-92 3.2 3.7 4.2 4.7
B+ 87-89 2.8 3.3 3.8 4.3
B 83-86 2.5 3.0 3.5 4.0
B- 80-82 2.2 2.7 3.2 3.7

Dual enrollment courses are weighted the same as an AP class unless you take a developmental class which I think counts as college prep. Gym/health aren’t part of the gpa

At our school:

Unweighted: Weighted (honors, AP, and IB):
93-100 is 4.0 5.0
90-92 is 3.67 4.67
87-89 is 3.33 4.33
83-86 is 3.0 4.0
80-82 is 2.67 3.67
77-79 is 2.33 3.33
73-76 is 2.0 3.0
70-72 is 1.67 2.67
67-69 is 1.33 2.33
63-66 is 1.0 2.0
60-62 is 0.67 1.67
0-59 is 0 for both

Class rank is not given, on the valedictorian and the salutatorian know their class rank. Class rank is determined by weighted grades. The best part is that there are honors, AP, and IB electives (that count for elective credits are are elective-type classes, i.e. music and art) so that you can maintain a 5.0 GPA even when you take electives. However Health (mandatory) and Phys Ed do not have weighted classes.
