YALL IM DYING

So basically I very stupidly chose to take precalc in my freshman year on top of Algebra 2(in US). In Cali, I was two years ahead and now I must get to that point too. AND OMG I SWEAR ITS KILLING ME. We have a marching band concert every other week and memorising the sets, the rehearsals. AND I KNOW ITS ONLY GONNA GET WORSE. Help me!
