A few things you may want to keep in mind when computing the bottom line value:
1) If they offer degrees in the area you want to study
2) If they tack on other hidden costs, like technology or activity fees for every course/semester
3) How many total credits are required for the degree - this can vary for Masters degrees and will impact your final investment
4) What previous credit courses you may transfer towards the degree, if applicable
5) For Masters degrees: If there are any restrictions regarding your previous Bachelors, such as GPA or subject area, and if you need any required testing, such as GRE or GMAT
6) Do they have any residency requirements (which will occur cost and hardship)
