About BandUp

Founded and made by Adam

BandUp was founded, designed, built and written by Adam — one person, not a company. Every test, explanation and word of it is written from scratch, so anything wrong or unfair is his to fix, and can be fixed the week you say so.

What BandUp is not

An independent study tool — not affiliated with, endorsed by or connected to IELTS, the British Council, IDP or Cambridge English. No band it gives you is official; they are practice estimates, to help you decide what to work on next. Every word of the material is original, copied from no published paper.
