In 2024, we opened NeuroAscent’s first three free levels to test our educational gaming platform. The calvarium level serves as the gateway to skull anatomy, guiding users through the bones and sutures that protect the brain.
222 users collectively tackled 4,721 questions about calvarium anatomy, maintaining a 71.51% accuracy rate while averaging 6.96 seconds per response. That’s a lot of skull bones. Be sure to read our recent post on the growth of our project over the years.
Calvarium Content
The calvarium level covers 34 anatomical structures commonly tested in medical school exams, with 151 questions spread across four difficulty tiers: 32 entry-level, 73 intermediate, 39 advanced, and 7 expert-level.
Beyond basic identification, the questions cover anatomical relationships (80), physiology (17), and clinical applications (18). Making these levels free in 2024 helped us improve both the framework and the content.
Level 1: Top Users in the Past Year
Here’s how our top users performed across both timed and flashcard modes. anyamalhotra answered 323 questions at 88.85% accuracy, earning 3,552 points. Snowlouette hit 93.25% accuracy across 311 questions. Lils24 averaged just 4.95 seconds per question across 200 attempts. m.brigger03 and Faithful each completed over 180 questions with accuracy rates above 75%. All five have earned extended access to the full set of skull levels.
Our timed mode gives users 90 seconds to answer as many questions as possible, with an algorithm that adapts question selection to each player’s difficulty setting. m.brigger03 leads the timed leaderboard with 317 points at 88% accuracy. ineedmedicine and StudentofSON followed at 76.19% and 81.25% accuracy, with Loki and varundvd rounding out the top five.
Selecting a higher difficulty opens up harder questions sooner in gameplay, which means more points per correct answer.

New CNS Surface Anatomy: Coming Soon
Next up: surface anatomy of the lateral cortex and brainstem. Three new levels, over 190 anatomical structures, and 493 questions. These cover content that shows up heavily on board exams and in clinical rotations.
Our top performers have received early access to these new levels. For free-tier users, full access is available through subscription. Thanks to everyone who’s played, reported bugs, and given feedback. We look forward to what’s next.
