Work out your GPA, what a final exam needs to save your grade, or roughly where an AP, SAT or ACT score lands, all in one place.
Everything here runs in your browser. Your grades are never uploaded anywhere.
Grades and test scores get treated as if they are single, simple numbers, but almost every one of them is actually the output of a small calculation with its own assumptions built in. A GPA depends on which scale your school uses and whether it adds weight for harder courses. A final exam question depends on how much of your grade that one exam actually controls. An AP, SAT or ACT score depends on a curve that changes from year to year and test to test. Knowing what sits underneath the number makes it far more useful than just watching it move.
An unweighted GPA treats every course the same, an A in a standard class and an A in an AP class both earn a full 4.0. A weighted GPA adds extra points, commonly 0.5 for Honors and 1.0 for AP, IB or college level courses, on the idea that a harder course deserves more credit for the same letter grade. Neither version is more correct than the other, they answer different questions. Unweighted GPA is what most national scholarship comparisons and some college admissions readers standardize everything back to, while weighted GPA is usually what shows up on your school transcript and class rank. When you are comparing your own number to a published average, check which version that average is actually using.
The final grade calculator on this page answers two closely related questions, and it matters which one you are actually asking. If you already know your target grade, it tells you the score you need on the final. If you already know your final exam score, it tells you the grade that produces. Both use the same relationship, your final grade is a weighted average of your grade so far and your final exam score, weighted by how much of the total course grade the final actually counts for. A final worth 10 percent moves your grade much less than one worth 40 percent, which is worth checking before you decide how much a single exam is really riding on.
AP exams are scored on a curve that the College Board sets separately for every subject and every year, based on how that year's test takers actually performed, not on a fixed percentage cutoff. The same raw score can land as a 4 one year and a 3 the next. The SAT, since moving to a fully digital and adaptive format, no longer uses a single fixed raw to scaled conversion at all, since the specific questions you see depend on how you performed on an earlier module. The ACT does publish conversion tables, but a slightly different one for every test form, so that a harder form doesn't unfairly cost students a few extra scaled points. The estimates on this page use a smoothed, generic approximation for exactly this reason, they are useful for tracking whether your practice is trending up or down, not for predicting an exact official score.
None of these tools replace an official transcript, an official AP score report, or an official SAT or ACT score. They are here to give you a fast, private way to check your own arithmetic and to understand what is actually driving the number in front of you.
