When a classmate starts an IGCSE Essentials or Pro plan from your link, their first month is free. Once they've paid for their first month, you get a month free too. Your link works for friends on IB, A Level and CBSE Math Revision as well.
Copy your personal link and send it to a classmate in your IGCSE class over WhatsApp, email, or the class group chat.
When they start an IGCSE plan from your link, they aren't charged for the first 30 days, on top of the usual free trial. They can cancel before then and pay nothing.
Once their first real payment goes through, a month's credit goes on your plan and comes off your next invoice. We email you when it does.
Terms: one free month for each friend who is new to Math Revision and pays for their first month; up to 12 free months a year. Not for school licences or class-code accounts, and you can't refer yourself. Links stay valid for 30 days after your friend first opens them.
