Since a pilot's job is never secure, having at least an A Level standard is ALWAYS an advantage... having a degree is yet a bigger advantage. Even after you obtain your pilot's licence, YOU must search for a job, and, the more qualifications you have, the more the employer would like you.
In addtion, if you want to work for an airline, most airlines nowadays do ask for A Levels, at least an A level in a science subject (Maths, physics, computing, chemistry..) or business.
I would not recommend starting your training for a pilot, with just GCSE O Levels in hand. My suggestion is to continue with your academic studies, and achieve your A Levels, then decide from there!
To sum up and answer your question, I'd say they are necessary.
Good luck!
