- Set 3: Set 3: 2026-02-03-Set-3-mixed.pdf
- Textbook work: Harder questions in 3.02–3.04.
- Comment: We've mostly finished Permutations and Combinations. Now it's just practice. We're not doing 3.05–3.07 in this topic.
- Comment: We did the handout "Permutations, combinations and counting questions" today. Answers are on Classroom.
- Textbook work: None today. We have a bit more to learn before digging further into 3.02–3.04.
- Set 2: 2026-01-30-Set-2-mixed.pdf
- Textbook work: Just easy questions for now. We'll get into the harder ones in Week 2. Do Exercises 3.02, 3.03, 3.04: just Q1–10 for each exercise. Feel free to skip some when it feels totally repetitive.
