Hi Jimmy,
As one of the guys said a few pages back, the only thing that differs between the three courses (basic, int and adv) is that they have different amounts of sorties(so basically as advanced you are expected to learn the stuff quicker than those with less experience). You also need to do a few more things as advanced (from memory I think low level ccts and glide approaches). If I recall correctly, advanced candidates also have to do a stall turn (which is usually the unbriefed aerobatic maneuver for basic and intermediate in the last "check/assessment" flight [some guys on my course had to do a half Cuban eight instead).
You can also use your flight experience as an advantage on your OSB, saying it shows your motivated with flying etc etc
Just make sure you go in with a clear mind, and don't lean back on old habits you may have from your previous flying experience. Make sure you attitude fly and not performance fly.... Oh and don't go to the imperial on the middle weekend
