Hi Mohammed,
If you get to spend 2-3 hours flying then your £290 will have been well spent as at £100/hr it may be some of the cheapest training you'll ever do (should you go on to pay for a licence from your own pocket).
If what you get is 2.5hrs of ground tuition and a half hour flight then you've probably been scammed and it would be interesting to see what made you one of the 1-in-20 (other than the fact that you paid up).
I'm sure we'll all be interested to hear how Monday goes!
