Frequently Asked Questions
SG O-Level vs IGCSE — are they compatible?+
80% overlap on the core; humanities differ more. AI auto-adapts to the track you pick.
A-Math vs E-Math — which one?+
JC track → A-Math is almost required. Poly business / design → E-Math is enough.
Does it support IP?+
Yes. IP students skip O-Level but the S1-S3 content overlaps fully.
Multiple kids?+
Pro covers up to 3 student profiles per family. Sibling sharing, no per-subject add-on.
Make L1R5 something you control, not guess.
