I didn't find it bad, I just got a bad result for some reason...?
I actually found the ODEs section the best, like I could do all of the tutorials for that really easily and I didn't even go to the lectures for that part. :/
I dunno. I only got 70 in 1902 and 71 in 1901, so I didn't do stellar in those either, but I did have a really bad time last semester, which is why I don't really get what happened to my marks this semester, I guess it was a bit of a snowball effect and stuff as well, but it really just comes down to needing to try harder.
Also going through the notes would've been helpful. lol
Or getting the textbook.
