NTTA exam, second time around

Hi everyone

I am about to take my NTTA exam for the second time (feb 16th) and i was wondering if anyone had any tips on revision? I obviously failed first time around, my biggest weakness is body and corrosion. I have been reading hillers fundementals and i am doing mock exams again but i feel as if i need some background knowledge on this subject to stand a better chance of passing this time.

Needless to say i am ectremly nervous going into it and i am dreading failing again as its a 2 year wait, so any help would be greatly apreciated.

I would also like to say thanks for all the usefull information ive already found on here, as its been very helpfull

Thanks
