      Why are you taking chem if you are desperate meaning you probably don’t want to take it and waste tons of money in college just to come out with no career? I’m not trying to be rude but it’s the truth.

    I'm at 2nd year high school being taught this Chemistry thing at our Science class. All we have base knowledge of is the periodic table and they gave us this whole gallon of knowledge in a very speeded up and rushed time. Plus, our Science teacher is one of the teachers you can sleep on lectures. It was hard to understand this one, since we barely caught up on the first lesson and our teacher was absolutely going fast because the class schedule will get restarted back to June and at the same time, everyone was sleeping in her class and she doesn't give sh*t about it. This video helped me understand it better, thanks!
