Raffles,
Firstly good luck with selection - you are quite right, selection is not just tough, it is cut-throat at present so be as well prepared as you can. If unsuccessful with GD P or WSO have you considered NCA? Cranwell do famil visits prior to selection - you may wish to take advantage of one of these. Contact TCO on Cranwell Ext 6699 to arrange. Also, as an aside, which AFCO was unable to assist in your enquiry? Not a witch hunt - the AFCO trainers here are always looking to improve their Cse/service to staff and feedback is always welcome.
Rgds,
JR
