## Realistic Prerequisites

- Experience with mathematical proofs was helpful but not required. Some students also appreciated previous exposure to linear algebra.

## Subject Matter

- The subject matter was very theoretical.

## Course Staff

- Students found the course staff
**caring** and **helpful**. - Some students didn’t find the lecturer very engaging.

## Lectures

- Most students learned most from completing the problem sets and reading the textbook.
- Lectures mostly focused on introducing and proving theorems found in the textbook.

## Problem Sets

- Many students found the problem sets
**difficult**, but doable using content learned in the lecture. - Problem sets required a higher level of mathematical maturity, and collaboration was helpful.

## Exams

**Stressful and challenging.** - The exams were considered difficult to finish on time but not totally unreasonable.
- Students found that the lectures and problem sets did not prepare them enough.

## Resources

- Most students found the textbook
*Linear Algebra Done Right* by Sheldon Axler to be incredibly helpful. - Recorded lectures were also available online.

## Grading

- Students felt that grading was
**not transparent**. - Students with less proof experience found the grading to be harsher.
- Midterms were worth 40%, the final was 30%, and problem sets were 30% of the grade.

## Advice to Future Students

*“This is a cool class for anyone interested in the “why” of math!”* *“Be ready to dedicate time to this subject if you want a good grade.”*
