How This Calculator Works
\n
This calculator helps you understand the relationship between your current AP score, the total points possible, and your desired score on the exam. It uses the following formula:
\n
Points Needed = (Desired Score × Weight Per Point) – Current Score
\n
Where Weight Per Point = Total Points Possible / 5
