I didn't say he shouldn't read them at all, and for Air Law you are probably correct. However for the rest too many people set too much store by question banks, and at this stage Nav420 should not even be thinking about question banks.
I would certainly have to disagree with you on HP&L, if only because I managed 98% without using a question bank. Mass and balance is an easy subject that it is also vital you can do. There is very little that is not relevant. If you know the subject enough to be safe then why do you need a question bank? As for comms, if you can't pass that without using a question bank then I don't wish to share the airwaves with you!
