Why we built this

Bring your course

Start with the course you're actually taking. Add your own syllabus, notes, and study materials when you want them in context.

Work one clear step

Your mentor helps you understand the next idea instead of dumping the whole course on you at once.

Practice and review

Answer, get feedback, revisit what you missed, and keep moving.

The material may be hard.
Learning it shouldn't feel impossible.
