Should I drop out of sixth form for an apprenticeship

I’ve just started the second year of my A-levels doing maths economics and photography. I’ve realised that I don’t actually like these subjects and am doing it just to please my parents and im not planning on going to uni whatsoever. after sixth form i was going to do an apprenticeship in vehicle mechanics but have just looked up that the cut-off date for applications are end of october, to start in novemeber. should i drop out of alevels this year and continue doing what im going to do after anyways now or should i finish off the year. i understand alevels would help in getting jobs but i dont plan on getting any jobs that require alevels and my gcses are sufficient enough.
