This is an open archive from my being a Waterloo and Laurier CS/BBA student.
If you find it useful and want me to endure more pain,
consider sending me a

Minus Stripe/PayPal’s 30¢ transaction fee, of course.
I make no guarantees that my work is remotely close to correct. Frankly, it’s more likely that it’s not. Please let me know if you find a mistake though! Or, in the spirit of open source, make a pull request fixing it.
If you want to use my
agony document class for \(\LaTeX\),
feel free to download it and look through the macros.

Quizlet flashcards are not mine: thank Imaad for them.
BUS 111 (F2020) Introduction to the Business Environment
Flashcards available for PEST factors and strategic expansion.

ECON 120 (F2020) Introduction to Microeconomics
No “practice”, but figured this is a nice place to host my cheat sheets. They are created on Figma, and the source files are available here.
If you just want the sheets, you can get them all at my Ko-Fi shop (which is, as always, pay-what-you-want). They remain on this GitHub repository too.
ECON 140 (W2021) Introduction to Macroeconomics
I hastily put together an equation sheet after lecture on the 4th. Let me know if there’s mistakes.
Cheat sheets are being provided on my pay-what-you-want store. Set the price based on your marginal propensity to consume cheat sheets.
Versioning is semantic: anything that is wrong/serious bumps the major version, aesthetic changes bump the minor version.

MATH 146 (W1989) Linear Algebra I (Advanced)
I found an old copy of my father’s Linear Algebra, 2nd edition by Hoffman and Kunze from when he was at Waterloo (and had the guts to take 14x courses). I have no idea if anyone at all would find these useful, but here are my solutions so far. Note that I use the notation from the book, which might hurt when MATH 136 starts.
Because it’s motivating or something, here’s a list of all of my mistakes. Hopefully it makes you feel better about yours. Thanks to everyone on the list who’ve helped me make this resource better for everyone :)
- MATH135/EP04/RP04 Messed up basic arithmetic (Roy)
- MATH135/EP03/RP09 Rewrote completely incomprehensible proof (Gabriel)
- MATH135/EP03/RP05 Proved a there exists statement by exhausting the domain (Angela)
- MATH135/EP06/RP05 Got the divides relation backwards for an incoherent proof (Quan)
- MATH135/EP11/RP03(a) Forgot the quadratic formula for a moment (Caitlin)
- MATH135/EP08/RP05 Totally forgot a question entirely (Javin)
- MATH135/EP11/RP01 Obviously, 2 + 1 = -1 (sooshi)
- MATH135/EP10/RP15(b) Overcomplicated proof when it follows almost immediately from the previous question (sooshi)
- ECON120/Final (v1.0) Deadweight loss of monopoly is between MC and demand, not price and demand (Jimmy Zhan)
- ECON120/Final (v1.1) Wrong colour on tarriff supply and demand curves
- ECON140/Test 1 (v1.1) NX curve description under AE curve section, simple multiplier given as A/Y not Y/A (Trisha)
