Grade 12: Computing
Start with a unit whose prerequisites fit. Work through the lessons, use the study guide to review, and try the new cases before continuing.
- Unit 1 · 4 lessons
Reproduce Analyses and Evaluate Responsible AI
Audit draft: "12 people completed; the tool caused 80%success; it won a prize." Evidence contains 12 completed attempts of 15 and nothing else. Rewrite it and state a review route.
Before you begin: Distinguish model output from evidence and read version labels.
- Unit 2 · 4 lessons
Design and Test a Purpose-Limited Log
Minimize collected fields, aggregate fictional events, test deletion and examine release risks.
Before you begin: Trace Boolean conditions and grouped counts; subtract whole-number day counters; distinguish internal use from publication.
- Unit 3 · 4 lessons
Compare Systems under Explicit Constraints
Compare a model with 40 tasks at 8 tasks/s, latency samples[1,1,1,1,8]seconds and a 50 Wdevice used 4 hours. Report duration,mean,max and bounded energy.
Before you begin: Divide rates and convert watt-hours to kilowatt-hours.
- Unit 4 · 4 lessons
Model and Review a Computing Capstone
Model a queue starting 2,with 3 arrivals then 1 completion. Compare predicted backlog with supplied observation 4,then decide whether an untested private-data requirement can be called passed.
Before you begin: Trace lists and distinguish tested observations from predictions.

The subject test uses additional supplied cases across these units. Its feedback links back to the relevant lessons. Use it to plan practice; a score on these questions is not a school grade or proof of complete subject mastery.
