integrals are a little bit harder to do than derivatives, but it's not that much more difficult.

In Calc II, you will learn more methods of integration. These problems are similar to some of the most challenging Calc I integration problems and perhaps more challenging. Just remember that each integration problem that can be solved has a particular strategy. Be sure to learn every strategy you can. You may also get into sequences and series and work on determining whether a sequence or series converges or diverges. Know the difference between a sequence and a series and memorize each of the tests for convergence/divergence that you will be taught. You may also be exposed to some introductury 3-d Calculus ideas. These will consist of a few simple formulas and techniques. Calc II is challenging because of the amount of material you cover. You really will have to devote two hours out of class for every hour in class. If you can devote the time to it, you should do ok.

I think Calc iii is harder than Calc ii and Calc ii is harder than Calc i

people say when u practice everything becomes easier...

But in case of integrals even if u practice its tough..(but if u don't practice u could never lift ur head up in that case...)..

You say that you hav got A in calc I then you won't find Calc II that much difficult .. anyways don't let it free to go..

Its in your hand to make a tougher one easier...
