How do you calculate gpa on a 4.0 scale?Answered
My school does it on a 100 point scale and im not sure on conversion. I got one 90, 91, 92, 93 and everything else above 95 (total of 17 classes i think so far). I saw that theres some place that makes an a- a 3.7 and some just having As as 4.0. Is it really important? My overall grade is about a 96.something and take 5aps 5 dualenrollment and some honors too. Thank you!

Common conversion methods
Simple letter cutoffs (no +/-) — often used:
90–100 = A = 4.0
80–89 = B = 3.0, etc.
Plus/minus scale (common) — example:
97–100 = A+ = 4.0
93–96 = A = 4.0
90–92 = A− = 3.7
87–89 = B+ = 3.3, etc.
Linear mapping (less common)
GPA = (percent / 100) × 4.0
(e.g. 96.5% → 3.86)
Your situation (you wrote: one 90, 91, 92, 93; everything else above 95; total 17 classes)
I’ll do two realistic calculations:
A — If your school uses the simple 90–100 = 4.0 rule
All 17 classes are 4.0 → Unweighted GPA = 4.00
B — If your school uses the plus/minus rule with 90–92 = A− (3.7) and 93+ = A (4.0)
90 → 3.7
91 → 3.7
92 → 3.7
93 → 4.0
the other 13 classes (you said “above 95”) → 4.0 each (I’ll treat them as A = 4.0)
Sum grade points = 3×3.7 + 4.0 + 13×4.0
= 11.1 + 4.0 + 52.0 = 67.1
GPA = 67.1 ÷ 17 = 3.947 ≈ 3.95
So with a typical +/- scale your unweighted GPA would be about 3.95 — very close to 4.0.
(If your school uses linear mapping, your overall percent ~96.x would give ≈ 3.86 as noted above.)
