Anything is possible, however you should consider the following.
Jobs in aviation are few and far between. Competition is extremely intense for the places that do become available. If you think otherwise, then spend a few happy hours reading these forums.
When competing for job placements and particularly attractive job vacancies, you are going to be up against people who will have attained a solid education foundation. Employers expect it. They see ample evidence of it every day. They will use it as a filter to whittle down the huge number of qualified applications to a manageable pile, from which they then make their selections for interview.
If you think education doesn't prepare you for the outside world, then you will quickly discover the harsh realities of what a lack of it is likely to mean.
The best advice I can offer you, is to stop kidding yourself, and knuckle down to achieving the best results you possibly can. That won't guarantee anything either, but having these basic weapons in your armoury will likely save you a lot of time and having to revisit these same fundamentals later in your early adult life.
