How do Favorites, Tags, and Notes help me study?

These features turn individual solutions into reusable study material.

Use Favorites for problems you want to revisit frequently. Use Tags to group related problems together. Add Notes when you want to record something you learned, an alternative method, or a reminder about a common mistake.

A useful workflow is:

Solve → Review → Save → Tag → Study

Over time, your Notebook can become a personalized collection of the math concepts and problems that matter most to you.
