<p>Calc 2 is harder because it is almost all focused on solving difficult integrals. Calc 2 is not cohesive instead it is more like a grab bag of random
topics. This makes it hard because every week you are learning a somewhat new concept instead of building upon what you already learned. One week you are doing differential equations and the next week you are solving sequences and series. There is also a fair amount of memorization needed for calc 2. But if you stay on top and study smart then there should be no reason why you will not get an A or B in the class.</p>
