For students to succeed in Vector Calculus, they must be proficient in exponents, factoring, combining rational expressions such as fractions with algebra, and solving equations.
You want to pay special attention to the Optimization Unit, which usually includes many word problems. However, if you have trouble dealing with word problems, be sure to prepare for this unit in particular. Do not forget to keep your notes organized while you identify the different kinds of problems. This will significantly help you to clarify the concepts in the course, and to keep track of your progress.
The concepts of vectors are very complex. So when approaching vector problems, be sure to layout and write down all of the steps clearly. Also, write down why such steps are necessary. For instance, what variable are you attempting to achieve with each step? This approach will undoubtedly simplify even more complicated questions and allow you to easily identify areas where you need additional help.
