I cannot create an account.

If you have applied for studies at the University of Opole already (as a regular or exchange student), you don’t need to create another account in IRK system. You need to create an account if you haven’t registered before or didn’t choose the option “I want to keep my account for the future registrations”.
It is important to use the real email which is often checked in order to receive all the messages from the IRK system.
If you don’t remember your password, use the “remind password” option giving your login email address. You will receive a one-time link to set a new password. Should you forget password to your personal email or have no access thereto, you have to visit the IT centre with your ID document in order to change the email. Note: the account with the PESEL number created earlier will hamper the attempts to create a new account.
