The KKU Academia sign-in link
The official link is registration.kku.edu.sa2, and you sign in with your university account in the form yourID@kku.edu.sa, not a separate account for the system.
What you do in Academia
Academia is the university's academic system: course registration with add and drop, the schedule, grades and GPA, the academic record, and e-requests. It opens with your university account.
Registration, add and drop open on the dates in the university's academic calendar, so if the registration button is missing, check the calendar before you contact support. Grades appear once the college approves them, and the academic record and documents are requested from the system itself or from the admissions and registration deanship, as the university publishes it.
When sign-in fails
Your Academia account is your university account, so a password comes back from the university, not from the system. At KKU that is IT reports1 and Support2. Check first that the account is active, that the password is the one that opens the rest of the university's systems, and that you are on the official link rather than a search result.
The rest of KKU: portal, email and learning
The same account opens the learning system (KKU Blackboard) and university email. Every sign-in link is on the KKU systems page, and the email guide is KKU university email.
For faculty
Grade entry, class lists and section schedules sit in the faculty side of the same system, with the staff account. The KKU systems for faculty and staff: Human resources1 and Research portal1.
After you sign in: student prices for KKU students
A KKU student verifies in tiswa with their university email and opens student prices on devices, software and subscriptions. Every deal is on the KKU student page.
