Depending on the program(s) you are applying to there may be a centralized application process or you will be applying to each program individually. Think in terms of not only does the school have the program of interest, but is it a program that you are interested in being part of. Research where the graduates have gone, the program strengths, the location, and the cost. Reach out to recent alumni from the program and ask them about their experience - the more information you have about a program, the stronger application you will have and the better able to target programs that fit you best.
