New materials for the 2025 course spec can be accessed under a new annual membership plan called Acute Angles Plus (AA+) Membership. It gives access to everything published on the site: the 2025 updated materials, the legacy 2018-24 “Out of the Box” course, and new lessons when we publish them. It also gives access to the student self-access pages.
Account holders with an existing “lifetime” membership to the 2018-24 materials can continue to access them via the “2018-24 CONTENT” tab in the main menu bar.
