When a classmate uses your link and subscribes to any IB Math Revision course, they instantly save €10 — and you get a €10 promo code emailed to you for your next purchase or upgrade.
Copy your personal link and send it to a classmate over WhatsApp, email, or the group chat.
When they open the link, our checkout applies a €10 discount to any IB course, SAT prep, PreIB, or bundle they choose.
Once their payment clears we email you a one-time €10 promo code you can spend on any product on the site — courses, SAT, bundles or a school seat top-up.
Terms: one referral credit per new paid customer. Discount can't be stacked with school licences, class-code redemptions, or the €20 summer/PreIB promo. Codes are valid for 90 days. You can invite as many friends as you like.
