Practice Exam 1 — Foundational • 93 marks • 150 min
Easy
P1. Consider matrices A = [[1,3],[4,2]] and vectors v = [3,4], w = [2,−1]. Compute det(A), A−1, |v|, v·w, and show v is an eigenvector of A. [14 marks]
P2. A spotted owl population is divided into juveniles, subadults and adults. Given survival rates of 53%, 73% and 89%, write the matrix equation pn+1 = Apn and project next year’s population from (21, 17, 53). [7 marks]
P5. Consider f(x,y) = 3x²y + y³ − 3x² − 3y² + 2. Find and classify all critical points as local max, local min, or saddle points. [9 marks]
P7. For the prey-predator system dx/dt = x(1 − x/2 − y), dy/dt = y(x − 1): find the three equilibria, fully classify their stability, sketch the phase plane with nullclines, and describe long-term dynamics. [17 marks]

SFU students who used it

★★★★★
"The practice exams were so close to the real final it was almost scary. I did all three before my exam and went in knowing exactly what to expect. Got a B+ after failing my midterm."

★★★★★
"Exam 3 is tough but that's the point. Working through it the week before my final meant the actual exam felt manageable. The solutions explain every step clearly — way better than just re-reading lecture slides."

★★★★★
"CA$29 is honestly nothing compared to what I'd pay a tutor. I studied from this for 4 days before the final and went in actually feeling prepared for once. Highly recommend to anyone taking 155."
