Isn’t a 4.0 more cosmetically pleasing than a 94? My school uses percentages. I have a friend at a nearby school that uses the 4.0 scale. We’re both straight A students, but her report card is gorgeous compared to mine. Her lovely 4.0 rows look so uniform next to my odd shaped numbers. It gave me 4.0 envy.
I heard that gpa: (%/20)-1
There is NO universal formula. If a school looks at 90-100 as an A, and every grade you have is S 92, you have a 4.0. Add all the 4.0s, divide by # credits.
The reason you have 4.0 envy is that there is little dufferentiation to be seen in it. That 4.0 could be a 91…or a 99%. It looks the same. But 99 is way more than 91 (last time I checked the math anyway!)
So if your average is 92%, it depends on what you got in EACH class. Convert that on the 4.0 scale, the average that. If your 92 is all 90 or above, you would have a 4.0. If it is some 96, 88, 94, 89, etc, it will be lower (4.0 + 3.0 + 4.0 + 3.0= 14/4 = 3.5).
If a school uses + and -, it gets harder to convert, but the math is the same.
Each school will convert at their own scale.
@HRSMom “The reason you have 4.0 envy is that there is little dufferentiation to be seen in it.”
No. As I posted, it’s because her report card looks prettier. I fully understand colleges dig deeper. 
^oh my. what is dufferentiation? Lol! iPads are so hard for me to type on!!
90-92: 3.5
93-96:3.75
97-100:4.00
Sucks their school is so hard not fair! Teachers suck and say things like “Oh, you kids are smart I won’t spend much time on this” and the smartest kid will say to herself “Freaking teach something!!”.
School is a joke these days and pay is through the roof. Community college jobs $48/hr give me a freaking break to teach online classes lol.
