will attendance affect my grades ??

Ive got poor attendance this year, about 76%. However, all my work/essays are completed on time, and receive consistent high grades. Will my attendance be a factor in deciding my final grade? This is for A-levels btw

I believe that the one thing where low attendance may stiff you is the fact that if you fall under a certain level (60% or something) then the school won't take you back.

I'm attending consistently from now on, there is no way they won't let me come. Im predicted A*A*A and I'm concerned if for some reason I'm externally looked at, my very low attendance but high grades might get me markedown or just look suspicious.
