AP Precalculus

Is AP Precalculus hard?

Most students who sit it pass: 80.8% scored 3 or higher in May 2025, and 28.1% earned a 5. What makes it hard is the trigonometry and polar unit, a third of the multiple choice, and free-response points that need a reason, not only an answer.

What makes it hard

  • Unit 3, trigonometric and polar functions, is 30–35% of the multiple choice, and some classes reach it late or rush it.
  • Part A is 29 questions in 65 minutes with no calculator, so exact values, factoring and log rules have to be quick.
  • Free-response points come in pairs: an answer and a reason. A right value with no justification earns one point of two.
  • Graphs carry many questions: reading where a function increases, how its rate of change behaves and where it is concave up.

How it compares, May 2025

  • AP Precalculus: 80.8% scored 3 or higher.
  • AP Calculus BC: 78.6%.
  • AP Calculus AB: 64.2%.
  • AP Statistics: 60.3%.

What makes it easier

  • The course is three units with published weights, so you know where the points are.
  • The same few ideas repeat: rates of change, transformations, and equivalent forms of each function type.
  • Part B allows a graphing calculator, and only some of its questions truly need it.
