Declaring a Major

I just changed my major my psychology to publie health and I am hoping that it was the right decision. I have alwasy been interested in issue involving health and I think that this is the right track for me to be on right now as I continue to learn and grow at school. I think it is hard for people to declare a major when they really do not know what it involves until they are enrolled in a university. Having the option of exploritory is a wonderful idea, this way is doesn't force people to declare a major when they are not 100% sure that this is what they want to do with their life. Ya, you can change your major, but if you do it too late you lose credits and may end up having to stay longer in school or be pressured into taking an overloaded schedule.
