When a classmate uses your link and subscribes to any IB Math Revision plan, 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 takes €10 off their first payment on any plan (Essentials, Pro or Platinum) or SAT prep.
Once their payment clears we email you a one-time €10 promo code you can spend on any product on the site — plans, SAT prep or an IA review.
Terms: one referral credit per new paid customer. Discount can't be stacked with school licences or class-code redemptions. Codes are valid for 90 days. You can invite as many friends as you like.
