<p>I’ve repeatedly heard on here and in my school, where AP Chem is a senior class and widely regarded as one of the toughest classes in our school, if not the toughest (the teacher plays a part in that too), but I’ve always wondered what makes it so hard. I wondered the same about calc and physics, and now I really understand why physics can be so challenging; I’m already struggling with it. But I want to take it next year (maybe, if it’s not too hard) and if anyone can give me some specifics I’d be grateful. Thanks!</p>
