<p>I barely got calculus the first time I took it at 16. (Got an A in the course but a 2 on the BC exam.) I took it again in college (I even took it self-paced) at 19 and I couldn’t figure out why it had seemed so mysterious 3 years earlier. I think it’s partly developmental, and partly that things are often easier the second time around. I agree with others though, if you are having difficulties this early in the year you probably need to bail. Is it too late to pick something else up? And second the others, dropping English is not an option.</p>
