The short answer
A new semester does not replace your earlier GPA. It adds new quality points and new GPA units to the same weighted average. That is why a first-year student's GPA usually moves faster than a senior's GPA after the same grades.
Worked example: 60 completed units
A student begins with a 2.800 GPA over 60 GPA units. A 15-unit semester at 3.700 produces 55.5 new quality points. The earlier record represents 168 quality points.
- Add the quality points: 168 + 55.5 = 223.5.
- Add the units: 60 + 15 = 75.
- Divide: 223.5 ÷ 75 = 2.980.
The semester raises the cumulative GPA by 0.180, from 2.800 to 2.980. If the student had only 15 earlier units, the same semester would produce a 3.250 cumulative GPA.

What makes the result move more?
- A larger gap between the current and new term GPA.
- More new GPA units.
- Fewer completed GPA units already anchoring the average.
