A quick concern

Hi, So i applied to all the pod schools in september when it opened and received interviews to all of them and went to a few in sept and october and got accepted to all the ones I went to. I have chosen to go to scholl next fall. However, since i am still a college student, i had to miss a bunch of my classes and it was very difficult for me to keep my grades high in my classes during the interview period and im struggling to get 2.0's in some of my upperlevel science courses right now. I mean I know I've already been accepted and am totally way past taking my basic science courses, but I can't help but be a worry-wart that the school will kick me out next may when they see my grades or something! I paid my deposit and everything (the school just told me i needed to send in my final transcript at the end of the year before i join and I'm all set). I'm not used to doing badly in courses but i just could not avoid it in classes with 2 midterms in the semester with me being gone and busy with other classes. But ya i think im worrying for no reason, but i just hate to slack off just because I got into a program. But ya what do you guys think? Do you think I'm okay?
