Main ideas & lessons

  • In problem-based technical classes, effective notes must capture both:
    • The sample problems the professor writes on the board
    • The step-by-step reasoning the professor uses to move from the original question to the final answer
  • Notes should include annotations/explanations showing why each step happens, not just a transcript of what was written.
  • If you don’t understand a step, you should follow up quickly to prevent gaps from accumulating.

Methodology / instructions (detailed)

  • While taking notes in class, capture:

    • The entire sample problem as presented.
    • Every intermediate step the professor takes from question → solution.
    • The reasoning behind transitions between steps (the “how you got from here to there”).

  • Annotate the notes actively (not neatly):

    • Use arrows pointing to specific steps.
    • Add short explanatory comments (e.g., “remember this is because…”, such as the reason a square root was taken).
    • Don’t worry about formatting; it’s okay to “draw all over” your paper if it helps understanding.

  • If you get confused at any point, act immediately using the “48 hour rule”:

    • You have 48 hours from the first moment you’re confused to resolve it.
    • Options to resolve confusion:
      • Ask during class right when you realize you don’t understand (raise your hand).
      • If you can’t ask during class, ask after class:
        • Go up and say: “I was confused about this step—can you explain how that worked?”
      • If you can’t speak to the professor right then:
        • Mark the unclear step in your notes with a question mark.
        • Bring it to office hours or email the professor/ask a teaching assistant.
    • Key principle: Start filling the gap as soon as you’re confused, rather than waiting until near the exam.

  • Avoid last-minute relearning:

    • Don’t wait until the day before the exam to reconstruct understanding.
    • Instead, do the learning as close as possible to when the material was first taught.
