Ersa and Paco, thanks for your replies.
This is driving me mad! I don't know what was wrong with the old way of doing things (apart from having to wait almost 3 weeks for your results

)
I applied to register for the portal on the 1st May, which was the first date that they opened the new system up. On the 7th May I received an email to say that I could apply for an e-exam, which I applied for straight away. On the 8th I phoned the CAA to query why I couldn't book an exam straight away, and spoke to someone who had NO idea what so ever, and fobbed me off ... grr.
I'm a bit confused as I looked up the exam booking deadline dates, which for the 2nd June is the 14th May ... Wednesday


, although i'm not sure if that is correct, as that may be the old system. I'm not sure but I think that I may have seen somewhere that you can now book an exam until 7 days before an exam?
I'm going to phone the CAA up on Monday and get it sorted, the CAA need to get there arses into gear, I have no idea how they expect to open a brand new system up (which may have teething problems) when the deadline for booking an exam is only 13 days later (including a bank holiday and weekends in between that where the CAA don't work ... god forbid

... poor little flowers!)Due to my own circumstances I have absolutely no chance of sitting an exam later than June ... getting a bit stressed now
