Hi friends,
I created freeieltsbooks.net.
This page is mine personally — it isn't part of that site, and it isn't affiliated with, endorsed by, or connected to IELTS, the British Council, IDP, or Cambridge Assessment English.
I passed the exam myself at band 8, and decided to share free English exam preparation books. They're free to download, with no sign-up and no account, at freeieltsbooks.net.
You can leave a voluntary tip here. It covers hosting, domain, translation costs — nothing is sold, and it isn't required to use any of the books.
Any amount, one time. It opens on their site, not mine.
