The 2020 AP Exams are open note/open book exams. You may also use musical instruments, metronomes, tuners, or digital resources to help prepare your answers.
Examples of free digital resources include virtualpiano.net, or any metronome or tuner app.
Please note that while you may use such resources in preparing your responses (including practicing your sight singing), your actual submissions must be created without such aids. You must submit an image of your handwritten notation for Question 1, and a completely unaccompanied, unaltered recording of your singing for Question 2, for either answer to be eligible for scoring.
