Hi Pillymonkey,
I definitely second what ARJM mentioned, if you are considering undertaking any study always get it confirmed first with DFR. I have heard of applicants completing extra study only to find out that it was not accepted for Pilot entry.
All the best of luck with your application. Also congratulations to ARJM on receiving an offer for PSF in Feb, I hope you can find someone to make contact with prior to attending.
