Accounting, Business Management, and Information Technology are probably three of the most well suited areas of study to pursue in an online environment. There are Colleges and Universities that offer degree programs in these areas where students may fulfill their degree requirements in a totally online setting. I completed all my junior and senior year classes entirely online.
Programs that require intensive lab-work are not well tailored as online offerings. Some of these include programs in biology, chemistry, and of course, medicine for obvious reasons. However, many institutions with programs in these areas offer online alternatives for selected program classes.
Students should check with their academic advisors or check the university catalog for details.
