AP Physics C, worked properly.

A growing library of fully worked AP Physics C problems. Every one states the answer first, shows the complete calculus-based working, and names the mistake that most often costs the mark. Built and verified by an IIT engineering graduate with 8+ years teaching this exam.

Mechanics
Vectors through oscillations and gravitation — the full sequence, taught in the order the exam actually rewards.
In production
Electricity & Magnetism
Electrostatics through inductance, same format. Routes and schema are already live so nothing has to move when it ships.

Answer first
You see the correct answer and letter before the working, so you can check yourself in ten seconds.
Every step shown
No "it can be shown that." The integral is set up, evaluated, and explained.
Traps named
Each problem calls out the specific error the AP graders see most often on it.
