I saw that holders of an International Student Identity Card (ISIC) can get a 5% discount when registering for the TOEFL. That’s really wonderful. A very long time ago I used my ISIC card to get deals all around the world. Mrs. Goodine even got an ISIC card when she went to grad school a few years ago. It warms my heart to know that people might use the same card to save on their language tests. Card holders can fill out a form on the ISIC website to get a voucher code to be used during the registration process.
Note that the offer is only available in “select” countries. I don’t know what those are, but LinkedIn says that the deal is available in 45+ countries in the EMEA region (Europe, Middle East, Africa).
