MDSC Discovery
Build your own MDSC
The redesigned MDSC Puzzling School programme launched in 2025 and enables you to customise your conference experience through our MDSC Discovery subjects. Instead of wasting time on boring puzzle placements, dissecting puzzles in the lab, or live in-person puzzling lectures, you can instead use our MDSC Discovery subjects to explore a wide range of other topics and interests.
Within MDSC Discovery, you complete several MDSC Discovery pathways for the chance to earn exciting MDSC Challenge points. Each Discovery pathway enables you to extend your conference experience beyond the standard MDSC programme.
As this year is the pilot year for MDSC Discovery, we have deliberately made the subjects easy, and we seek your feedback on its implementation.
MDSC Discovery rollout
- There will be five Discovery pathways, each composed of several subjects. To progress within any given pathway, you must complete subjects in order.
- Two pathways will be released at 10:00am on each of Mon 23rd June and Tue 24th June.
- At 10:00am on Wed 26th June, the final pathway will become available, along with a feedback form.
- Struggling? Assistance for each subject will be released 24 hours after the release of the subject's pathway.

Student support
We are dedicated to supporting you through this transition period as we completely up-end the MDSC curriculum and use you as guinea pigs. We understand that this may frustrate or upset those of you who enrolled in MDSC Puzzling School to do some actual puzzles. Students experiencing any issues with MDSC Discovery can direct all enquiries to mdscpuzzles@gmail.com.
