Resources and extra materials.
If you need to brush up on your Calculus skills, there is a nice set of lecture notes by Gregory Naber, containing several examples, at:

http://www.gregnaber.com/lectures/calculus/

If learn things best by seeing tons of examples, you should have a look at the textbooks "Schaum's outline of Partial Differential Equations" (or one of their variants), which contains more than 1000 solved problems. It can be found in the library or bought at a reasonable price on Amazon.
