Our tutors write for their own lessons: a breakdown of a set text, a maths paper pitched at one year group, the explanation that finally landed with a student on a Tuesday afternoon. Rather than leave that in a folder at one academy, we publish it.
The English half is free and has been for years. Around 15,000 students a year use those guides, most of them sitting the HSC, and you do not have to be a BTA student to open one. No account, no email address, no payment.
It is not a sideline either. These are the same pages our tutors build lessons from, which is why they are specific about a text or a module rather than general advice about how to study.
