Not wanting to 'rain on your parade', sorry for the americanism, but I think the previous poster has a very valid point.
If you were hour building up to this point and not practising accuracy for the CPL course, then having to revisit the very basics at this point seems to me as if you may well have a bit of an uphill struggle.
Two weeks? Hmmm.
Do keep us posted as i'll be interested to see how it turns out. Remember, these schools are there to make money from students, they aren't charities, but then again, if your flying isn't up to standard before starting the CPL course, then you pretty much only have yourself to blame.
Look forward to seeing your progress reports.
