Curation standard
Quality over raw volume.
A weighted score ranks candidates on syllabus weight, past-paper frequency and diagnostic value.
Drawn from real past-paper patterns
Drawn from the active bank and scored on syllabus weight, past-paper frequency and diagnostic value. The score favours high-frequency concepts; not every item is a past-paper question.
Filtered for core conceptual understanding
The selection favours questions that expose common misconceptions and test principles rather than superficial recall.
Worked explanations and trap analysis
Each question explains why the correct option is right. Where the explanation includes distractor analysis, it names the trap.
Structure
Each question carries the reasoning behind the answer.
Worked explanations for the correct option, with distractor analysis where available.
Trap analysis highlighting the specific misconception behind wrong answers.
Integrated into spaced repetition flashcards for automatic revision.
Included in every MDCAT Pass at no additional charge.
Learning science
Designed around how memory works.
CRUX is built on proven principles of retrieval practice and spaced intervals.
Spaced Review & Long-Term Memory
Cepeda et al. 2006Spaced review across multiple days produces significantly better retention than cramming. CRUX automatically schedules missed questions into your review queue.
Active Retrieval Practice
Karpicke & Roediger 2008Testing yourself on difficult questions creates stronger memory pathways than passively re-reading notes or textbooks.
Misconception Feedback
Butler & Roediger 2008Explicitly identifying why an incorrect choice is misleading leads to higher scores on subsequent tests.
Desirable Difficulties
Bjork 1994Practicing with challenging, high-quality distractors feels more demanding but builds reliable test-day confidence.
