All i can say is, just do what you want to do,
if you have something in mind and have a passion for it,
just do it!
Who cares if you have physics or how old you are
theres no limit in learning how to fly,
and me myself, as a 16year old, i'm currently a student pilot trying to get my PPL
i have no physics background other than knowing, work= force x distance
If you're thinking of making cash out of it,
it doesn't have to be out of big airlines,
once you get your CPL you are able to make profit with that license,
as in you can find a job with it. Things such as, sightseeing tours.
PS: you don't need to know how to spell, but you do need to know how to communicate verbally, in a clear and "understandable" way,
just my final words are: Just do what you want to do. When you get too old and you fail the medical exams, thats when you regret.
