F5 Addmaths OTC (June 2025)

What Will You Learn?

• In Lesson 1 (5/6/2025), students will be introduced to Chapter 4: Permutations (Part 1), beginning with the concept of arrangement without repetition. The lesson will cover foundational permutation principles. Students will explore various types of permutation questions, such as arranging letters, digits, or people, and apply logical reasoning to determine the total number of possible outcomes. This builds a strong base for more complex cases introduced in subsequent lessons.
• In Lesson 2 (12/6/2025), students will continue solving a wider range of permutation problems, progressing to more complex scenarios such as: permutations with restrictions (e.g. certain items must or must not be together), circular permutations (e.g. arrangements around a table), situations involving identical items (e.g. repeated letters). The goal is to build versatility in applying permutation formulas and reasoning in diverse question contexts. Students will also be exposed to SPM-style structured questions to develop exam-readiness.
• In Lesson 4 (26/6/2025), students will take a break from Chapter 4 to engage in targeted revision of Chapters 2 and 3, ensuring mastery of earlier topics before continuing with combinations.
