Find one-to-one Grade 12 computer science support for the Ontario curriculum. Start with the skills your child is studying, use short practice tasks to find gaps and build a plan around the next school topic.
Ontario sets the learning expectations for this pathway. Your school’s unit sequence and language of instruction also matter. Share the textbook, topic and recent feedback so lessons match the work in class.
02
Building confidence in computer science
Trace a program before running it. Track how values change and test ordinary, boundary and invalid inputs. An algorithm should explain a repeatable method independently of a specific interface. Lessons can alternate a modelled example, a question attempted together and an independent attempt so the tutor can see where understanding changes.
03
Use school feedback to guide revision
Bring a recent coding task, trace table or test case. Explain where you got stuck. The next practice task should check that particular skill before introducing more complexity. Tutoring supports learning; assessed submissions remain the student’s own work.
Understand it. Try it. Review it.
Put your computer science learning into practice.
Worked example · Algorithms, Python and debugging
What does this Python code print? total = 0; then for n in [2, 4, 6]: total = total + n; then print(total).
Start at total = 0.
After each iteration the total is 2, then 6, then 12.
