Chem before AP Bio?

Hi Guys,

So I had some problems in my scheduling, and it finally resulted with me having an open spot. Two days before school started I asked my counselor if I could take AP Bio and she barley found me the spot. The problem is that Pre AP Chem is a prerequisite for AP Bio, and i am enrolled in both courses simultaneously. The counselor said if my teacher is fine with it I could go on. I was wondering if not taking Chem before hand would really hurt my grade in AP Bio… A lot of people say its not that much required, only in the first few chapters. I dont know what I should do. Should I stick to taking both AP Bio and Chem simultaneously or switch out to some other class. The problem is that most classes are full now, so I would have to take some really dumb class instead. Thanks!
