• Registered nurses are some of the most in-demand professionals and are well paid for this. Becoming a registered nurse requires taking plenty of science courses, but you can become a certified RN in as little as two years.


    The classes you need to become a registered nurse depend on how far you plan to advance in the field. Registered nurse programs are offered at the associate and bachelor's level, as well as certain hospital degrees, reports All Nursing Schools.

    Getting into a Program

    Entering a nursing program after high school usually requires 3 years of math and science and 4 years of English in high school with a minimum of a 2.00 grade point average, reports All Nursing Schools. Actual standards and SAT scores vary from institution to institution.


    Nurses practice nursing theory in an actual clinical setting, but they also take several science courses, such as anatomy, chemistry, nutrition and psychology. In addition, they need lots of math to prepare them for measuring medication doses, reports the U.S. Bureau of Labor Statistics.


    In 2006, the average RN made between $47,710 and $69,850, according to the US BLS.


    Entry-level RN jobs will often pay for you to take extra classes to receive a bachelor's in nursing, according to the Bureau of Labor Statistics.
