Frequently asked questions

APPhysics.si is an AP Physics mentoring service. Each student works 1-to-1 with a human Physics mentor, supported by our Physics Intelligence Engine, software that assesses work, tracks concept mastery and adapts practice between classes.

"Super Intelligence" (SI) is our name for the Physics Intelligence Engine that supports mentors. It combines a map of AP Physics concepts, deterministic physics and maths checking, and AI models for reading written work. It is not literally superintelligent, and it does not replace the tutor: the tutor makes the teaching decisions and can override any assessment.

AP Physics 1, AP Physics 2, AP Physics C: Mechanics and AP Physics C: Electricity and Magnetism, following the unit structure of the current AP course frameworks.

The diagnostic is a short adaptive assessment for the course you choose. Question difficulty adjusts as you go, and results are weighted by difficulty and concept rather than counted as a simple percentage. You get a mastery profile, the prerequisite gaps we found and a suggested starting point.

Yes. Every mentoring student has a human Physics mentor. The software prepares information for the mentor and handles practice between classes.

Numerical answers are checked with deterministic calculation and unit analysis. Written and free-response work is scored point by point against a rubric, with the evidence for each decision recorded. Every AI assessment carries a confidence level, and anything below the review threshold goes to the mentor before it counts.

No. Nobody can honestly guarantee an AP score. We show an internal readiness indicator based on demonstrated performance, which is clearly labelled as ours and is not a prediction of an official score.

No. AP is a trademark registered by the College Board, which is not affiliated with and does not endorse APPhysics.si. Our questions and explanations are written by us or used under licence.

We collect only what we need to teach. Students under 18 need a parent or guardian to approve learning analytics and AI processing, and students under 13 must be signed up by a parent. Student work is not used to train AI models. You can ask for a copy of your data or for it to be deleted from your account page.

Linked parents see classes completed, assignments, a plain-language summary of strengths and areas needing attention, upcoming classes, payments and mentor-approved reports. Private mentor working notes are not shown.

Classes are online and 1-to-1. Times are stored in UTC and always shown in your own timezone, so families in different time zones see the right time.
