As a student you get two accounts for the use of IT facilities.
These accounts give access to the student portal and the Odisee MyDay app, your Odisee-mailbox, the electronic learning environment Toledo, the PC’s of Odisee, My Admin, WiFi, access to the website of the Standaard boekhandel (bookstore) to order your textbooks and course materials, …
You first need to activate both accounts before you can use them. When you registered you received a letter with both your accounts and activation codes.
The ICT service will gladly help you further.
