Stressed!

Just handed in an assignment at 5pm... It was a report and well, it was due at 5pm, and it took so long to load my assignment - at least 15 mins to upload... So when it was finally handed in, it was 5:15pm. I was scared about incurring a late penalty submission so I emailed my lecturer anyway. Not that that will help my score in that assignment cause I seriously think it was done crappily. Like for starters, the tables took so long to calculate and draw up and then to insert it into Word that I nearly gave up. This was done the whole of yesterday. And last night, I was writing up the report with hardly any sleep - did a sleep for about only 4 hours. Had one nap from 5-7am and then from 8-10am. It felt like me doing a thesis all over again. The only difference is that with a thesis, you come up with the research topic... this report was killing me cause I didn't really understand it. And I can't believe it is only worth 10% - so not worth that mark. I'm thinking I flunked it though cause I didn't formulate any hypotheses, or rather, my hypotheses were really obvious, and then I got lazy towards the results section and said "as you can see below, this was.... (blah blah...)" So practically describing it without really comparing or explaining. And now upset that I couldn't get more time to do it. Not that I didn't plan out my schedule properly. It was more that I had so many assignments and so little time. And now I have an exam on Thursday which I haven't studied for yet. Hopefully I make up for marks in the exams... Am just suffering pre-exam blues at the moment, and post-assignment traumatic stress.
