Why is my grade curved? Once the total composite scores are calculated, Collegeboard curves them differently each year to keep consistent standards and regular pass rates, which means we can only estimate based off of previous years. Why use AP Pass? I use only past released exam formulas published by Collegeboard, which makes AP Pass the most accurate and up-to-date calculator available.
