Help! I'm taking Calc II this semester and its been years since I've taken Calc I and even longer since I've taken Trig and Pre-Calc. I need a quick but in depth review because I seem to have forgotten everything. And I mean Everything. I was completely lost in class today and I've never felt like that in a math class in all my life. I've loved math since I discovered geometry and I've always done exceptionally well so I have no doubt I can reteach myself everything but I haven't found a good website or anything. Any suggestions?
