Last week, I went on vacation Monday-Thursday, and missed school. Friday, I had no idea what was going on, partly because of my usual lack of sleep, and partly because I was missing most of a very busy week of classes.
Why was that week so important you ask?
It was the week before midterms, where the classes which only last 1 semester have a sudden rush of work before they end, and it was the end of the quarter, where you suddenly realize you didn't hand in that essay that you should've, because your teacher didn't it grade when they should've, so they did it right at the end of the quarter and put it in the gradebook late, so you didn't realize that your grade dropped 15 points. This was that lovely week of reviewing everything in every class right before a massive test, all while catching up on that work you completely "forgot" to do.
Back to my original point: I missed most of that week.
Surprisingly, I've done fairly well on my midterms so far, even Physics (to my surprise), but that's because I already had most of my review material and (sort of) knew what I was doing.
Sadly, I've screwed up in that part where you hand in work at the last minute, and my English grade isn't doing too well. Physics and Economics could be better too.
So long story short, don't take vacations when you're really busy, because it can only make things worse. Also, don't try to do schoolwork on a plane. People will bother you, the noise makes it impossible to think, and the wifi is so bad that you can barely load a webpage. And if that webpage is webassign, then it simply won't work at all.
Finally, one last lesson, don't expect it to be warm down South during a giant winter storm sweeping across the country, because even if you're in Houston, it can get below freezing. When I was down there, I checked the weather in Houston vs the weather in Rochester, and they were the same: 20oF. The entire city shut down because they weren't prepared to deal with the ice.
