Sec 1 & 2 EMaths Foundation Lessons
This course is designed for Sec 1 (S1) and Sec 2 (S2) students in Singapore who will eventually sit for the GCE O Level Elementary Mathematics (EMaths) exam in Sec 4 (S4). The lessons focus on foundational topics that form the building blocks for learning EMaths. This course is separated from the Maths For GCE O Level (SG) Course because these topics are tested directly only at the S1 and S2 levels; at higher levels, they are assessed indirectly as part of broader concepts.
Students preparing for other examinations, such as iGCSE, GCSE, or high school assessments, will also benefit from the concepts and skills covered.
