Which course gives the biggest GPA return for the same grade improvement?

Enter your term's total credits and, for each course, its own credits and the quality-point improvement you are imagining (such as moving from a B to an A). This ranks the courses by GPA effect only; it does not tell you which improvement is realistic.

e.g. 1.0 for a full letter jump like B to A, 0.3-0.7 for a plus/minus jump

How we calculated this

Each course's GPA delta is its own credits times the quality-point step you imagined, divided by your total term credits, the same math a course-grade-effect calculation uses. Using the example values above (a 15-credit term, a 3-credit course with a one-point step, a 1-credit course with a one-point step), the 3-credit course moves your GPA by 0.2, while the 1-credit course only moves it by 0.0667, since the same quality-point improvement in a higher-credit course carries more weight in the overall term average.

Limitations

This only measures the mathematical GPA effect of an equal-sized quality-point improvement; it says nothing about how realistic that improvement actually is in each course. A 1-credit course might be far easier to raise by a full letter grade than a demanding 4-credit course, even though its GPA payoff is smaller here.

Common mistakes

A common error is assuming the same quality-point step is equally achievable in every course and ranking purely by the numbers here without weighing actual difficulty or effort required. Another is entering a step size that does not match how grade scales actually work at your school (some schools use non-integer jumps like B+ to A-); use your real quality-point scale's actual increment.

Frequently asked

Does a higher-ranked course always deserve more of my effort?
Not necessarily; this ranks by GPA math alone. Combine it with your own sense of how achievable each course's improvement actually is, and see Study Hours by Course to translate priorities into an actual time split.
What if two courses tie for the same return?
They are shown in the order you entered them; a tie means the GPA math genuinely does not favor one over the other, so use other factors to decide.
Can the quality-point step be a fraction?
Yes; use whatever step size actually matches the grade improvement you are picturing on your school's real quality-point scale, including fractional plus/minus increments.
Does credit count alone decide the ranking?
Only when every course uses the same step size; a smaller step in a high-credit course can still rank below a larger step in a lower-credit course, since both credits and step size determine the delta together.
