Smithy my man,
My point, rather than to confuse, was to suggest there are a multitude threads on this topic, a few on this page.
Dentistry, along with the other qualifications mentioned above, are by no means neccessary. There are many pilots out there without A-levels, although they tend to be a reasonable measure of ones commitment to learn (by modern standards). This is a must.
Have a search, weigh it up, and crack on my friend.
Kind Regards
CR
