For advance theory, if you're going to rely on that blue book
only, in my opinion, it is not enough to handle the
questions.
I suggest you attend the revision class, it's quite helpful. During
the class, you can clarify any doubts with the instructor also. And
I guess you might be facing problems with questions that deal with
manual gears and clutch, so by attending the revision lesson, you
might be able to understand better on the manual car
controls.
And when you're doing practice, pay more attention to the correct
answers.
