I agree the BGS notes are highly lacking in depth. But if you've ever read the OAA notes, they go into far too much detail.
I believe the BGS notes are brief because they rely on the student backing up knowledge using the question bank. If you remove the Question bank from the equation, I find it hard to believe how anybody could pass their exams using just the BGS notes. There needs to be a middle ground.
The BGS CBT is also just a verbalised version of the notes, word for word. It needs some work.
You'll notice on certain (most) pages, there are small boxes with key information you need to know. These are basically the areas the questions are on. It's a convienient way of compressing the notes to give you the basics, plus the answers to questions.
Not great, but young students that don't like learning stuff can't get enough of it.
