As for my medical, I've not got a class 1 as yet but I've had both my doctors and opticians confirm in writing that I can pass the requirements as stated on the CAA web site.
Unless either of them is a CAA licensed medical examiner, this isn't likely to mean very much.
Even then, it's not the same as actually
having the Class 1. The only piece of paper that counts is the one you get from Gatwick.
Before you do
anything else - and certainly before you start borrowing money - go and get your medical sorted.
