Oh the frustration

I am completely irritated with school right now.
We just started a new trimester and I have most of the same classes I have had all year. But this tri I'm taking another online class. I was enrolled in the class over a week ago and the class still doesn't show up. So now, since the class started on Monday, I'm another week behind. On top of the 2 weeks I already had cut off because I'm graduating at the end of May.
So now I have 9 weeks to do a 12 week class. And I don't know how I'm going to have time to do that with all the rest of my homework and getting ready for AP tests and getting ready for graduation and my job. I know that I will, most likely, be in situations like this while I am in college. And it's not that I can't get it done because I can and I will and all will be fine and well. It's just frustrating. I have wasted 7 hours this week trying to get into my class that I should have been put into last week sometime. And what makes it even worse is that the conselors don't know what's wrong with the class and why I haven't been put in it yet. They have emailed and phoned the instructor and have gotten no response.
So now there is nothing left to do but wait. And I hate waiting around doing nothing when I know that there is stuff I should be getting done. I can't handle this for much longer.
