Calculus is a tough subject to get used to. It's quite different to traditional math, especially in terms of the application problems being wildly more difficult. There are many concepts you will be expected to memorize (mainly for derivatives), but most are fairly simple to remember, but are difficult to apply. The key to most math courses is to do a lot of examples. If you don't understand a problem or example the first time you read it, don't stress too much. As you practice more, you will find the questions are easier and easier. Try to get used to doing math without a calculator as in this course and many more in the future, you will not be allowed to use them on tests.
