Mechanics, vibrations and waves, fluids, heat and thermodynamics, electromagnetism, optics and modern physics.
Each article is labelled with its level (secondary school / university general physics) and includes conceptual diagrams to help you build intuition and absorb the concepts.

The topics overlap almost entirely, yet the requirements are fundamentally different — the same map, zoomed to a higher resolution.
Mechanics, waves, heat, electromagnetism, optics, modern physics — secondary school and general physics essentially follow the same map, so it often gives the impression of "I've studied this before".
In secondary school, people ask “what is it, and how do you calculate it?” and apply formulas to get answers; in university general physics, people ask “why, where does it come from, and where are the limits?” and use calculus to derive results from first principles.
Read in this order, from mechanics all the way to modern physics
