Calc 2: More-difficult integration techniques (integration by parts, trigonometric substitution, partial-fraction decomposition), infinite series. Most people find Calc 2 the toughest because of the infinite series. Calc 3: Multivariate calculus, partial deriv…
These are highschool courses or? We did that in highschool (allthough it was repeated in university as well). I suspect the russians are learning that in primary school, because they are so good at math. ;)
