What is the Highest GPA Ever in the World? Record Holders & How They Achieved It

The highest GPA ever recorded is 11.84, achieved by Dylan Mazard. This record comes from a weighted GPA system that gives extra points for advanced and honors-level courses. While it’s far above the standard 4.0 scale, it shows how weighted grading can push GPAs much higher when students take the toughest classes available.

Who Holds the World Record for the Highest GPA?

Dylan Mazard holds the world record for the highest GPA ever recorded.

He was a student at Gaither High School in Florida. Dylan earned a weighted GPA of 11.84, which is the highest GPA reported worldwide. This record was possible because his school used a weighted system that rewarded honors, AP, and advanced classes with extra grade points.

How Did Dylan Mazard Achieve an 11.84 GPA?

Dylan Mazard reached an 11.84 GPA by earning high grades across a huge number of advanced and college-level classes. His GPA wasn’t about one perfect semester. It was the result of how many classes he took and how early he started.

Here’s how it worked mathematically:

• Started advanced classes early
  Dylan began taking high school–level courses as early as middle school. Those grades counted toward his final GPA.
• Used dual enrollment (college classes)
  He took college courses while still in high school. These classes carried more weight than regular courses.
• Took up to 14 classes per semester
  Most students take 6 to 7 classes. Dylan took nearly double that load, stacking weighted points every term.

Because his school used a weighted GPA system, each honors, AP, and college course added extra grade points. When you combine early credits, dual enrollment, and a heavy course load, the GPA adds up fast. That’s how the number reached 11.84.

Is a 10.0+ GPA Actually Possible? (Weighted vs Unweighted)

Yes, a 10.0+ GPA is possible, but only on a weighted GPA scale.

A standard unweighted GPA stops at 4.0. That means straight A’s. An A in gym counts the same as an A in calculus. The class level doesn’t matter.

A weighted GPA works differently. Schools give extra points for harder classes. This is how numbers like 11.84 become possible.

Here’s the simple breakdown:

• Unweighted GPA (0.0 to 4.0)
  All classes are equal. An A always equals 4.0.
• Weighted GPA (5.0 and higher)
  Extra points are added for tougher courses, such as:
  • AP (Advanced Placement)
  • IB (International Baccalaureate)
  • Dual enrollment (college classes)

In Dylan Mazard’s case, his school gave much higher weight to college-level courses. By taking many of them, his GPA moved well past the normal limit.
