ICS4U Computer Science (Grade 12)
The Grade 12 U-level computer science credit: modular and object-oriented design, classic algorithms with real complexity analysis, recursion, and a capstone project substantial enough to talk about in a university application. Waterloo CS and Toronto EngSci applicants live and die on this mark.
Inside the course
Modular design and object-oriented programming
Searching and sorting algorithms; efficiency and Big-O
Recursion and recursive problem solving
File I/O and structured data
Capstone software project, designed and documented
Where it leads
Named or expected by competitive CS and software-engineering programs; the capstone doubles as portfolio evidence for AIF-style supplementary applications.
Assessment & credit
Standard Ontario assessment: 70% coursework, 30% final evaluation. Completion ships as an official transcript, OUAC-listed and recognized by public and private schools.
How we run it
Small groups, online or in person (Markham campus); semester, summer and winter intakes, scheduled around the student’s Top 6 plan.
