Topics

Topics is for browsing public catalog exercises by subject area.

Use this page when you know the mathematical area you want, but you do not know the exact wording of the exercise. Topic browsing is especially useful for large subjects where the same idea may appear in many different exercises.

Topic List

The Topics page shows root topic areas from the public catalog. You can:

• search topic names
• scan the list of available topic areas
• open a topic to browse its aligned exercises
• request a topic when the area you need is not available

The topic search on this page searches topic names. It is separate from exercise search.

Topic Detail Pages

Opening a topic takes you to that topic's exercise-browsing page.

A topic detail page can include:

• a topic header
• a Topic outline for subtopics
• exercise search
• filters for content state, exercise type, difficulty, and review status when available
• results for the selected topic or subtopic

The outline lets you narrow the page to a more specific topic level. When you select a subtopic, the page focuses on exercises aligned to that part of the topic tree.

When to Use Topics

Use Topics when:

• you know the subject area but not the exact exercise wording
• you want to browse related concepts before searching
• you need exercises across several textbooks or sources
• you want to narrow public catalog content by concept

Use Catalog Search instead when you know exact words, phrases, or an exercise ID.

Tips

• Start broad, then use the topic outline to narrow.
• Add a search term after choosing a topic when the topic still has many exercises.
• Clear filters if a topic looks empty but you expect results.
• Use All Exercises when you want to search published community exercises without starting from a topic.
