Re: Best Way To Study?

I read the textbook after the lectures to make sure I really grasp what he wants us to know and then I do the homework problems. The modules are also extremely helpful because you can pause/slow down the video lecture to make you understand the concepts.

Re: Avogadro's number

You usually divide by Avogadro's number when the question gives you the number of molecules and is asking you to find the number of moles of a compound.

Re: Rusty on High School Chem [ENDORSED]

I haven't taken chem since sophomore year of high school so I am in a similar position. One thing that I've been doing is reading the textbook pages that correspond to the lesson because I think it gives me a wider understanding of the topic.
