IGCSE Maths Tutoring for Jesselton International School Students
Kota Kinabalu
Common Challenges
Functions and Inverse Functions
Many JIS students reach Year 11 without confidently understanding composite and inverse functions — topics that carry significant Extended-tier marks and require a conceptual leap beyond basic algebra
Graph Transformation Recognition
Identifying which transformation has been applied to a graph, and writing it in transformation notation, is consistently answered incorrectly due to insufficient visual practice
Exam Structure Unfamiliarity
Students unfamiliar with how Cambridge marks multi-step answers miss method marks they are entitled to because they don't show working at the right level of detail
How Teacher Rig Helps
- Functions taught with input-output diagrams before formal notation, making composition and inversion intuitive
- Graph transformation library built over several sessions — students develop a visual vocabulary that makes recognition automatic
- Mark-scheme annotation practice: students learn exactly which lines of working earn marks and which are superfluous

My child finds functions very abstract — can you make it clearer?
Yes. Teacher Rig teaches functions using a concrete input-output model first, then connects it to formal notation. Almost every student who was confused finds it clear within the first session on this topic.
How is online tuition different from watching YouTube videos?
YouTube is passive — your child watches but doesn't do. In Teacher Rig's sessions, your child works through problems live, gets immediate feedback on errors, and can ask questions in real time. The difference in outcome is significant.
