Peter Roach - Phonetics

has anyone here read Peter Roach's Phonetics (Oxford) and Peter Roach's English Phonetics & Phonology (Cambridge)?

I'm supposed to have an oral exam in the former, but I've only read the latter and I haven't figured it out up until a few moments ago.

How fucked am I?

I've read neither. I have, however, familiarized myself with situations wherein an individual can be fucked. You're probably in one.

I'd recommend pimping google or amazon for a .pdf or downloadable copy.
