The Erudt University Open Academy offers free short courses at academy.erudt.com. Anyone can create an account and start a course the same day.
The courses give applicants a feel for the pace and style of Erudt teaching before they apply for a degree, and give professionals a quick way to refresh a skill.
Learners who complete a course and pass its assessment can request a certificate that can be checked online.
An Open Academy account is separate from degree enrollment. Students who later join a degree keep their Academy history.
The full catalogue is on the Academy site.
