Astronomy...

Way early in the semester, I missed this one astronomy homework assignment... so I have a zero for it and it really is disappointing to look at. But if I had completed that, my homework average grade would be around a 97%... and, with that, it's 87%. I wish I could go back in time and do it... I have no idea how I missed it, I just didn't remember to do it, cause it's online. It was the third homework assignment (out of about ten or eleven) and it's incredibly frustrating.... so, yeah. There's that. I can't believe I missed it and it's costing me THAT much.
