Online assessment practice

Timed OA sets

Two to four problems against the clock, graded on hidden tests the way campus drives, HackerRank and CodeSignal-style assessments are. Finish and you get a score report with what to practise next.

How it works

The clock starts when you press Start and keeps running if you leave the page.
Two sample cases per problem are shown in full. The rest are hidden: you see how many passed, not what they were.
Partial credit counts. Each problem keeps your best submission, weighted by difficulty.
No hints, editorials or coach during the attempt. They come back in the report.
