Your transcript probably shows two numbers. One is capped at 4.0, the other climbs past it. Which one lands on your application? The honest answer is neither — at least not exactly. Colleges almost always recalculate.
The two numbers, plainly
Unweighted GPA ignores course difficulty. Every A is a 4.0, every B a 3.0, and the ceiling is exactly 4.0. It's a clean ruler that treats an easy A and a brutal AP A as the same achievement.
Weighted GPA rewards difficulty with bonus points, typically +0.5 for honors and +1.0 for AP or IB courses. That's why a student in all-AP classes can hold a 4.3 or a 4.6 while their unweighted number sits at 3.9.
Why colleges don't just take the number
Every school weights differently. Some cap weighted GPA at 5.0, some at 6.0; some drop plus-and-minus, some keep A+. Published scholarships and applications accept GPAs from dozens of different systems. To compare fairly, admissions teams rebuild your GPA on a single internal scale from your actual course grades.
The number on your transcript is what you earned. The number on your application is what the college recalculated.
What they actually evaluate
Recalculated GPA matters, but it sits inside a broader picture that includes rigorous coursework, trends over terms, and class rank. A student with a near-perfect weighted GPA who avoided every hard class sends a very different signal than one who earned 4.2 while taking AP Physics and Dual-Enrollment Calculus.
So which should you track?
Track both. Your unweighted GPA is your honest baseline; your weighted GPA shows effort. Use a GPA calculator to see them side by side, blended with your past terms — that's the picture colleges are piecing together too.
