The Memory Lab review

The Memory Lab has grown 18% between 5 Sept 2026 and 1 Nov 2026, by its published member count. It is sold as a single purchase rather than a subscription.

A review on the numbers, not an opinion: nobody here has joined The Memory Lab, and nothing below is a verdict.

The Memory Lab is a Skool community and study program for people learning nursing, medicine and the allied health sciences, and for teachers of those subjects.[1] It is run by Justin, a life science teacher who makes Siebert Science on YouTube, and it focuses on how learning works and how to study more effectively.[1] The group was created in May 2025.[1]
