Completely opposite experience with me when I had my assessment in 2007. I did modular training and my MCC was on TP. Was fortunate enough to pass thankfully. In fact I'm fairly sure that there were no integrated guys on my TR course.
That said most of the cadets I bump into these days do seem to have done an intergrated course at OAA or similar so maybe times have changed.
Best of luck with whatever route you choose.
