One should use common words to say uncommon things.

This project is not a textbook.

It is a structured study system designed to help you learn concepts in order, review individual topics, practice with focused problem sets, and follow guided prerequisite maps.

No filler. No empty history. Just direct learning, rigorous reasoning, and proof of understanding.

If education is truly universal, then anyone can become an expert. What matters is not where you start, but whether you can prove what you understand with rigor.
