LE/EECS 1520 Mock Final Examination
York University • Course-style practice set • 65 multiple-choice questions
Built from lecture topics, assignments, and publicly available past-style practice materials.
Time allowed 110 minutes (recommended for practice)
Format 65 multiple-choice questions; some
questions specify “Select TWO answers.”
Topics emphasized Digital/analog concepts, binary/number
systems, Excel formulas and chart logic, R
code output, functions, loops, matrices/data
frames, ggplot.
Recommended use Attempt closed-book first. Mark uncertain
questions, then review with the answer key
on the last pages.
Instructions
Choose the best answer unless the question explicitly says “Select TWO answers.”
For R and Excel questions, determine the exact printed result, returned value, or graph
type.
Assume standard R behavior and standard spreadsheet relative-reference behavior
unless stated otherwise.
For random-number functions, focus on the type/shape/range of output rather than exact
numbers.
