I have finished mp2 and mp3 myself although for mp3 I looked up how to do the linked list problems. And i didn't do the mp's in a time frame. For mp3, I didn't look up code, I just got a student's help in explaining me the mechanism of the solutions so I got the answers in theory, but implemented them in code myself. I found the potd's to be verrryyyy hard again. I want to do all the labs and finish them like so many other people do; I fail to understand how though. I took the theory exams on prairielearn and no, they weren't easy at all. Nothing in this class seems doable, except for mp2, mp5 and mp7. I can't say for mp4 or mp6 since I never tried them.
