Review Instructions

Please review this concept list carefully before proceeding to the next step:

  1. Check for missing concepts - Are there important topics from the course that should be added?
  2. Check for irrelevant concepts - Are there concepts that go beyond the scope of Circuits 1?
  3. Verify label quality - Are labels clear, concise, and under 32 characters?
  4. Check for duplicates - Are any concepts redundant or overlapping?

Making changes now will save significant effort in later steps. It is much easier to modify the concept list than to fix the dependency graph later.
