The links below will grant you direct access to the various subscriptions. Do note that you will need to be logged in but your education account number assigned will not be needed.

SAP Learning Hub - direct access

SAP Cloud Certification - direct access

SAP Live Access - direct access

NOTE: You will still actually need to have a user within these systems (this is usually your logged in account), by using these direct links though, the normal license checks are bypassed, and if your subscription has expired the relevant learning system will not grant you access.
