Computers is a six-credit first-year course that enrols more than 250 students each semester. Until 2020/21, attainment was determined by a single 90-minute paper examination in which each candidate blindly drew three open-ended questions. In-person proctoring was difficult, hand marking up to 1,000 answers per term was labour intensive and subjective, and the grading pressure peaked during the three-week examination period. We report a four-year digital transformation that replaces this model with a fully autograded, Moodle-based workflow delivered under Safe Exam Browser and reinforced by compulsory face-to-face ID checks. The new exam combines fifty one-point and ten five-point items drawn from randomised question pools, including live Falstad circuit simulations, yet retains the 90-minute duration. A continuous assessment route, two mid-semester tests unlocked by achieving at least 11/20 laboratory points, now enables most students to pass without the final exam. Across seven cohorts (2017–2024), the pass rate rose from 60% to 72%, manual marking fell by two orders of magnitude, and no confirmed cheating incident occurred. The remaining failures are dominated by students who do not meet the test entry threshold, rather than by zero scores or withdrawals.
