## Secondary Maths Classes in June

2 JunWe are opening maths revision sessions (and hopefully science…) this June holidays. Per session will be based on particular topics in the secondary maths syllabus with a *seat capacity of only* **3 or 4 **(*min. 2 pupils* to start a session). You may expect selected question analysis, concept elaboration and application in each session. Sec 4s can expect topical questions selected from prelim papers (it’s just 1-2 months before prelims). Do sign up early by arranging registration and payment with us before the sessions are occupied! A session of the same topic may be opened for sign up on another day in June (subjected to our tutors’ lesson schedule). For payment and registration, kindly send your enquiry to admin@matharena.com.sg and upon confirmation and verification through payment procedure, we will register for you and you can just come for the session(s) on the date(s) assigned.

**Disclaimer:** Below is the schedule of the revision session (accurate as at May 26). There will be updates every weekend so do save this link onto your phone (or any tech device) to keep up with the updates.
