AP Calculus AB
The AP Calculus AB exam is 3 hours 10 minutes long and split evenly: 42 multiple-choice questions worth 50% of your score, and 6 free-response problems worth the other 50%. A graphing calculator is required for Part B of the multiple choice and Part A of the free response, and banned in the other two parts. The course itself is 8 units, from limits and continuity through applications of integration.
Nuros gives you the whole of AP Calculus AB: a worked note for every topic in the 8 units, practice that marks your method rather than just your final answer, and full-length practice exams that show exactly which concepts are costing you marks — then drills them until they stick.

Study AP Calc AB in a loop, not a straight line
1. Learn it
A structured note for every topic in the course, with worked examples and diagrams rather than a wall of bullet points.
2. Test it
Unit quizzes and full-length practice exams in the real paper format, with written answers marked against the rubric rows rather than checked for a keyword.
3. See the gaps
Every attempt updates a mastery score per concept, so the feedback names the concept costing you marks instead of handing you a percentage.
4. Close them
ARC — the Adaptive Review Cycle — re-explains the weak concepts and brings them back on a spaced schedule, with fresh questions, until they hold.
AP Calculus AB questions students ask
3 hours and 10 minutes in total — 1 hour 40 minutes for the 42 multiple-choice questions and 1 hour 30 minutes for the 6 free-response problems.
Only on two of the four parts. A graphing calculator is required for Section I Part B and Section II Part A, and is not permitted for Section I Part A or Section II Part B. Practising both ways matters: the no-calculator parts are worth 68.3% of the exam.
AB covers less ground — BC adds series, parametric and polar work on top of the AB content — but the questions on shared topics are pitched at the same level. AB is a full year on the same material BC moves through faster.
