grade with your own rules, ab/bc for ap calc, and more

september 27, 2026

AP Calc now separates AB and BC content, so BC-only material stays out of AB practice. Teachers can write grading rules that override AP scores where they grade differently.

For students

  • Choose AB or BC for your Calc course. Pick your course on FRQ practice, guided practice, or a diagnostic, and BC-only topics (like Euler's method or parametric equations) stop showing up in AB practice. Practice AP Calc
  • Pages load steadier. Study guides, cheatsheets, the top nav, and the timed paywall stop jumping around after they load, and FRQ practice pages are lighter and faster.

For teachers

  • Grade with your own rules. Write a grading standard for an FRQ type — say, requiring three pieces of evidence where College Board accepts two — and Fiveable scores every response your way, with the AP score still there for reference. See the Teacher Workspace
  • See real graded results before you sign up. Pick your subject and see a sample assignment with real student essays, scores, and feedback, so you know what grading looks like before building your first quiz or importing essays.
  • Filter questions by College Board skill. Build a quiz or browse FRQ/SAQ prompts by the exact skill you're teaching, not just topic and unit.
  • See which submissions came in late. Assignment results now show a Late chip with how far past the due date a response landed.

Content updates

  • Steadier AP Lang synthesis scoring. The sophistication point on synthesis essays is scored more consistently, and it no longer goes to an essay that only repeats a tension or tradeoff a source already points out. Practice AP Lang

Fixes

  • Teachers who stayed logged in for weeks no longer get silently signed out — sessions renew while you're active, and a signed-out assignments page says so instead of looking like you're still logged in.
  • Your typed FRQ practice response no longer disappears if you switch to handwriting mode and back.
  • Retrying a slow checkout could create a second subscription and charge you twice. Fixed.
  • FRQ scoring keeps working even when an AI provider has an outage, instead of leaving essays stuck.
