I don't know enough about your situation to really give the advice you probably need.
That said, I can offer a few suggestions based on this, and personal experience. The first things you should probably do are eat and sleep. I'm in college too. I know what it's like to just get caught up in work and stress and not maintain myself like that. But when I make time for sleep, and enough of it, I feel a lot better, and am generally more productive. Same with food. You can even study while you eat, so you're not really losing much time at all that way.
If you're having trouble finishing work because of the volume, I get the impression you're overwhelmed by the volume and are either skipping around, or rushing through stuff. If that's what's happening, I'd recommend calming down and taking things one at a time. If it's just a normal assignment, then sit down, do it as well as you can, and be done. If you have a lot of reading, do it in stages. I know for my one French lit class, I just had to read a 400-page novel. I read it all during any chance I had for a week. I'd read it whenever I got a seat on the bus, during a lot of my meals, in class before they started (and during, but that's not good advice >.>).
When it comes to exams, the same kind of strategy should help. Take them one at a time. If you have 3 exams in a week, think of it day by day. I know when I have weeks like that, I'll study what I can the weekend before for all of them, but once the week starts, I'm only thinking about the next exam, not the ones after it, until the first one is done. And yes, it is stressful and hard. It's not easy, and I don't follow this advice nearly as well as it sounds. But when I do, it does work out better. Hope some of this is helpful! Feel free to ask more. I'll try to check back, but if I don't and you want to, feel free to message me.
Thanks for responding.
If I eat and sleep then I have less time for work and turn in even more incomplete assignments. The work is too hard anyway. Even operating at full capacity I can't do it.
I feel like I could crank out 400 pages in seven hours. That's a page a minute, plus 20 minutes to goof off. You had 168 hours to do it. I don't know, but it seems like you had plenty of time.
I do assignments one at a time, and yes I rush through it: otherwise I'd get a zero on something else. The five minutes I'm spending on this post probably equates to about 1/4 of one problem for a given class (out of like 10) so I'm not losing too much.
"As well as I can" isn't aywhere near good enough. That's the entire problem. If I was smart like everyone else I could crank out this work in a reasonable amount of time.
I skip three classes. For one, I notice I learn just as well and faster reading the book and doing the hw. One class is easy and there's no HW, so I don't waste my time preparing for it. The other class I usually intend to attend, but I'm caught up finshing the homework for that class during class so I can turn it in by the end of class.
I'm doing homework the weekend before. Here's my "to do" list
Study for stats exam (should take like three hours since I haven't been attending class)
Cot HW: will beat my head against it for an indeterminate amount of time. It's math; there's no partial credit or half-right answers
CDA: HW Will probably fail anyway, but I have to try
Take trip to walmart
Eat once: fill up water bottles
EEL prelab and studying for lab
EEL HW
Read EEL textbook
Then it's monday and I have new stuff assigned during the week and the cycle repeats. I never finish entirely on the weekend so I have to rush to do stuff before its due.
I'm a good test taker, though, so that helps make up for the utter lack of knowledge.
I'm about to break, but if I fail, then I'll starve to death on the street. It seems like life is a horrible hellhole and there's nothing I can do to fix it. Again, nobody else has the same volume of problems because they understand stuff so they work faster.
i'm sorry you've had a bad week
