How to calculate GPA from 100 point Scale?

Looking at the college board gpa conversion chart, a bunch of grades are grouped together in a range all assigned to a particular grade on a 4.0 scale. How then, do people calculate GPAs of 3.6 or 3.94? My school doesn’t calculate gpa so how do it myself? The conversion chart doesn’t seem accurate.

You don’t need to. Just use the info from your HS and the colleges will convert if they need to.

As Erin’s Dad said, you don’t need to convert it for applications. If you would like to convert it just to see if you are targeting the right schools for you, try inputting your grades on raise.me

My daughter moved schools after her sophomore year. The first high school was the US News #1 STEM public magnet school with a 0-100 grading system. We moved internationally for work, so the second was a German International School with an IB program that has a 0-7 grading system. We never knew what her 4.0 scale GPA was. Colleges admitted her anyway and gave her merit scholarships. The only glitch we had was our State Public U that had an automated system for scholarships based on self-reported data. An email to admissions cleared that up and she was also awarded merit.

My point is, don’t worry about it, the colleges figure it out.

Agreed, you should not recalculate into a 4.0 scale. Your HS will send a school profile along with the transcript which explains the grading system, te levels of classes offered etc… College admission officer are used to dealing with all different kinds of grading scales so they will figure it out. FWIW my D’s HS program did not give grades, just written evaluations, and colleges seemed to handle that just fine.

Thanks everyone! I guess I was just wondering for myself so I would know what to plug into niche scattergrams and the like?

In which case, this is as good as any.
