Read full description

Preparing for the OLNA? This is a mobile app built specifically for Western Australia's Online Literacy and Numeracy Assessment — the reading, writing and numeracy tests you need to pass for your WACE. PRACTISE UNDER REAL CONDITIONS • Full-length timed mocks: 45 questions in 50 minutes, matched to the real test format • Non-calculator numeracy, just like the actual OLNA • Exam-mode writing: autocorrect off, 600-word limit, 60-minute timer AI FEEDBACK ON YOUR WRITING Submit a practice essay and get instant, criterion-by-criterion feedback on audience, structure and organisation, vocabulary, cohesion, sentence structure, punctuation and spelling — the same areas markers look at. KNOW WHERE YOU STAND Track reading, writing and numeracy separately and see whether you're on track for Category 3 before test day. Only study the components you still need to pass. BUILT AROUND EVERY WINDOW Countdowns and reminders for each OLNA window across Years 10–12, including the compulsory Year 10 sittings. Five minutes on the bus or a full mock at your desk — study anywhere, no laptop required. OLNA Prep is an independent study aid. It is not affiliated with, endorsed by, or approved by the School Curriculum and Standards Authority (SCSA).
