Every section of the test
Not just maths
The Selective test has four papers. Most apps cover one. Cognora covers the lot.
Reading
Comprehension, inference and text analysis across fiction, non-fiction and poetry.
Thinking Skills
Logic, argument analysis and critical reasoning — the section most students have never seen.
Abstract Reasoning
Pattern and sequence recognition for HAST and scholarship entry.
How it helps
Built around what your child gets wrong
Adaptive difficulty
Questions adjust in real time to your child’s accuracy and speed, so practice stays challenging without tipping into frustration.
Smart Mistake Bank
Wrong answers return later inside fresh questions — the same concept, a different wrapper — turning mistakes into lasting understanding.
Full mock exams
Complete, timed papers that build exam familiarity and take the edge off test-day nerves.
Progress you can see
Accuracy, streaks, weak topics and score trends in one dashboard built for parents, not spreadsheets.
