Hey @Jaefan98! Welcome to the forum!
So the Unreal Academy is a large paid service, usually paid for by a company for their employees as training, or for schools. It is largely group-based and tailored for your needs. If you are seeking free classes, that is what the Epic Developer Community is. 
(Link to that located here)
Now, if you are part of a company or group that has access to Epic Academy, that is different. The Unreal Academy Account Manager would be the one in charge of the account from your company/school/group, as far as I am aware!
