I sat my first 8 exams last month (through BGS) and was very happy with the standard / style of the questions available from the online question bank. Suffice to say I was not unduly shocked to turn over the first page of the exam in the exam room.
If you can:
understand the questions and what they are actually asking (sometimes quite hard!)
work out the answer (be it by theory, mnemonics or just memory recall)
work with accuracy / speed
generally understand all of the concepts studied
I would suggest you will be fine come the exams.
Don't just rely on the question bank, it is a useful additional tool that probably has people who studied a few years ago green with envy. Plus the price is probably the best value for money around.
