Practice in the real exam format
About two-thirds of your score comes from questions with no calculator, so on timed exams Desmos stays off the screen for those parts, just as it will on exam day.
| Part | Questions | Time | Calculator | Score |
|---|---|---|---|---|
| Section I, Part A | 29 multiple choice | 62 min | No | 35% |
| Section I, Part B | 13 multiple choice | 38 min | Yes | 15% |
| Section II, Part A | 2 free response | 30 min | Yes | 16.7% |
