The first thing you need to see is what kind of commitment each university requires from you. Some programmes will be more based on research and will have little in the way of classes where as others will require you to have more classes as well. You need to see whether you schedule allows you long hours at the university, especially if you are doing a job. Can you leave the job for the Ms or do you have to juggle both of them at the same time. If so, you will have to get into a university that gives you a flexible schedule.
Programmes on Offer
You must also make sure that the university that you are considering offers the majors that you are interested in. This will allow you to move in the right direction. Continuing education in the field of your liking and the sub-field of your preference is very important and can be instrumental in motivating you to move forward.
Everyone has an idea in mind that how much time they want to spend while they complete their Ms. Seek a program that fits in your time table or is closest to it. This will be useful as you will be on schedule for your future plans.
Although you may get the program of your liking, you must make sure that the program will help you in getting further employment and also makes a bit of an impact on your professional future. Do consider if you want to do a PhD, will it help you? The standing of the institute is crucial and must be considered.
Style of Testing
Is the testing based on overall semester performance or solely on the final exam? Will you be judged on your research only? These questions must be answered and one should know what he or she is comfortable with.
