Trying not to be intimidated

So school started this week and Biology seems to be pretty hard. I have a new teacher and she is just so hard to understand she is all over the the place and just talks in circles and we do lab in our class and we all rush the counters for space its just really different than i thought. we are doing chemical compunds now and just all sorts of different crap . For some reason she believes we all have taken chemistry which is not the case because biology is the pre req for chemistry so we had to inform her of that! so Im just gunna dig my head into my book and hope I get all this down. Not to include i have 80 pages a week of health to read and essays due! yikes i know I can do it so i just gotta try and not get intimidated and overwhelmed and look at the goal I will reach and that we will then be able to send oputr kids to college and lice comfortable, not to mention i will be saving lives all the time how cool is that!. Wish me luck...school is frickin hard.
