Worst student EVER

For my physics class it is a mon/wed/friday class but because I work nights back half of the week going to class on friday is like going to lecture at midnight for me. So I don't go it is just not worth it unless there was a test or an assignment due. It sucks because this is the only time this year this class is offered. Having no selection bugs me.

Anyway, last week I was going to due my homework while I took my car in to get fixed because I didn't really have anything else planned but that and community group.

Didn't happen

I hurt my ankle that night too so I didn't want to walk on it wednesday so much because I have to stay on my feet alot for work so I didn't go to class. I figured I could do that homework that I put off

Didn't happen.

So today I got up early and worked on the homework that I put off, turns out that while I was gone they assigned another homework assignment that is due in about 15 mins. I tried to work on it for a while but it is about xray defraction and though I was in some of the lectures and read the notes it looks like jibberish to me. The homework isn't graded but there is a test on wednesday and if I don't understand the concepts if there is a test question that isn't just plug in numbers to an equation I'm so sunk.
