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 think you misunderstood me.
I already read the Cambridge one. I need the Oxford one to see if they cover the same grounds since I'm supposed to have an oral on the Oxford one, and all I've read is the Cambridge one.

tl;dr
"And that won't suffice?" That's what I'd like to know.
