I myself have not missed a day of school. But I feel like if I were to I would miss a lot of information and I would be very unhappy with that. But I know some people that have to miss a day of school once in a while, but they have a very strict absence rules. So if you know you're not going to be there then maybe you should take a different schedule. I know that there are evening classes and that there are morning classes and the times never change for the morning classes and the evening classes. There's a specific time when you should be there at a specific time that you should leave. When you enroll, they tell you the hours that you will be attending school everyday. So there should really be known reason to miss because you should plan ahead. As far as transferring credits, I haven't had to transfer any credits but I heard that it's not very easy to, a lot of people are denied so they have to retake the classes that they have already taken somewhere else.
