221 2023W1 was…..if you know you know. Trauma. I think about it every day and sob.

Legit nothing taught in class helped on exams. It was like the person writing them thought the class was an advanced abstract linear algebra class. Course content will fool you into thinking the exams will be manageable.

Out of 200 people only 20 showed up consistently. I don’t think I heard him finish a single thought of his. He also mumbled and just couldn’t teach (probably because he thought the course material was too easy).

Just don’t take it!

No piazza support. No support material to practice for exams. All textbook. No annotated notes. Hard exam. There wasn't even a TA and another guy from the math department had to come in and help on piazza.

linear algebra, transformation, sys of eq. Is used in different maths

Mumbles. Not responsive via piazza. Gave barely any resources. Didn't even hire a TA. Forces you to read the textbook.

For practicing exams, find the bank of exams by the math department and visit old math 221 canvas pages (not easy to find) to get the practice exams. Studying is all done by you.

Very hard course by Macdonald. No help on piazza. The lectures are only him reading off a textbook. No practical examples. Very little practice material given. Exams had to be picked up in person. The only way to get an A is to read the textbook for hours straight and to salvage old canvas pages for practice material.

Basis, dimension, orthogonality, eigenvalues, eigenvectors. Lots of proofs

Doesn’t help on piazza. Doesn’t give practice material. Doesn’t explain concepts well. Doesn’t hand back exams unless you go in person
