<p>I'm just wondering if anybody has any good sites or books that teach a subject like chemistry, physics, calculus, etc? Obviously the professor would be the best resource, but I'm looking for a few sites that could help me now and later. Right now I usually go on youtube and watch videos on chemistry but they are not detailed as what my class learns.</p>
<p>I didn't even know YouTube had subjects like chemistry on there.
I might be using them later on.</p>
<p>Anyway, I usually try to find books on Amazon and look for the highest rated one, or I'll visit the websites of instructors at other colleges; they usually put some sort of slideshow online for their class and in most cases, I've found their material to be more helpful than my college's</p>
