so our HS uses a 5.0 unweighted scale and 6.0 weighted scale. How do I get that to a 4.0 unweighted scale? I've seen multiple different ways online. Our HS system seems really unfair. Any student who has 16 "advanced" credits gets a 1.2 multiplier. No distinction if you took honors home economics or AP Physics, Chem, Calc etc. Or if you only took 16 advanced credits or 24. They're actually changing it to make it a lot better and more fair, but it doesn't apply until the class of '28 unfortunately.

Does each university do it differently? I've seen some say an A is a 4, B is 3 etc and calculate like that. Then some have different numbers for A+, A, A- etc. Then some have a dif value for a 90, 91, 92 etc. What's the standard for scholarship apps, college apps etc? The top reference on google says an A+ and A are 4 but an A- is a 3.7.

I'm not sure if our son has a 4.0, a 3.99, a 3.7, 3.5 or what. I want to make sure we're doing it right but also not putting him at a disadvantage on anything where it asks for an unweighted 4.0 GPA but doesn't provide guidance on how to calculate it.

My kids go to a private school. This is the scale their school uses. The school states, "(school name) has adopted a modified version of the College Board 4.0 scale. The ajustment aligns with the most frequently used scale utilized for college admissions."

Hope this helps.

The "percent grade" is the raw grade for the unweighted GPA. The raw grade is adjusted to get to the weighted GPA. For AP classes they add 10 difficulty points to the raw grade and for an "advanced" class (usually available to freshmen and sophomores) they add 5 difficulty points. This is done on a class-by-class basis.

Thank you that does help. I've seen that one before but wasn't sure if it was the correct scale to use. That's the one published on the College Board website.
