What course are you planning to do with OAT? If APP then I can assure you that the syllabus content I have described is accurate at the time of writing. Note that I'm quoting mostly single-engine IFR totals; there are 5 hrs ME/IFR & I stand completely by my remarks concerning the applied I/F training out in the U.S. I am not suggesting that the I/F training conducted abroad is in any way substandard, only that the environment is different to the U.K.
I'm unsure of the source of your information but I can tell you that it sounds as if you may be confused about the course content. If you contact OAT & enquire about the single-engine VFR/IFR content they should clear things up for you.
Regards
