• Qualitative feedback:

  • (misc) Team exercise solution sets are graded and you do get feedback.

  • Positives:

    • Group work ++++…
    • Labs, videos, etc

  • Challenges (as eloquently stated by one respondent):

    

    • Not enough time. I’ll switch to 15 minutes, though I think the later quizzes tend to go faster anyway.
    • Not sure what/how to study
      • Material from prior Friday, Monday, and Wednesday.
      • What should you know? See the Goals at the beginning of each lecture video.
    • Other feedback: scores do not reflect knowledge; trick questions; etc.

The midterm is Friday (5/6) of next week!

• The exam will be most similar to the quizzes.
• Study advice:
  • See how to succeed
  • Slight elaboration:
    • Know the Exercise content cold.
    • Practice solving problems; for those involving code, write it on paper then type in and debug.

Today’s Problems have Goals, so please get through the Exercises efficiently.

• The big takeaway is that AVL trees provably have height O(logn)! Yay!
