Is Mathesis down right now?
Learner reports build the picture here, and Mathesis down reports rise when enrolment or exam week opens. The Mathesis status line tracks whether the course platform answers across Greece. A test deadline pushes hundreds of students onto the same screens at once.
Note which part failed for you. A catalogue that loads while videos stall tells a different story from a full sign-in failure. The split guides the repairs listed under the fixes heading.
Is Mathesis down for me or everyone?
Open the course catalogue in a private browser window without signing in. Public pages that load fine while your dashboard fails point at your account session. If the catalogue itself stays blank for others too, a Mathesis outage explains the freeze.
What a Mathesis course week looks like
Each week releases a set of lecture videos with reading material and a short test. Students move at their own pace inside the week, but the test closes when the week ends. The course page shows the current week and the units still open.
Discussion boards under each course let students ask the teaching team questions. Answers there often solve the same doubt for the whole class.
How weekly tests and the final exam count
Weekly tests check the ideas of that week and build the habit of steady study. The final exam covers the whole course and decides the completion mark. Both run inside the browser, with the clock shown on the exam page.
Inside the certificate request and payment
After a passed final exam, the platform offers the certificate for a small set fee. Payment runs through a secure card page, and the certificate then appears for download. Students who are unemployed request the same certificate free through the course page.
Where your course progress is stored
The progress page totals finished units, test scores and the share of the course covered. It updates after each submitted test, not after videos alone. A unit marked open usually hides an unsubmitted test at its end.
Common Mathesis Problems and Fixes
Mathesis faults cluster around enrolment days and exam hours, when the platform carries its heaviest load. Match your stuck screen to the step below it.
Enrol button spins and does nothing
Wait for the course start week, since enrolment opens on the course schedule, not at once. Refresh the course about page and press enrol once, then check your dashboard. A course already on your dashboard means the first press worked.
Weekly test refuses to submit
Save each answer as you go, because the page stores answers only after the save step. Submit before the weekly deadline shown on the course page. A late test closes for marking even when the videos stay open.
Lecture video stops and starts
Lower the video quality inside the player settings during busy evening hours. Pause for a short buffer build before pressing play again. Download speeds on shared home Wi-Fi dip when others stream at the same time.
Certificate payment page errors out
Check that the card allows online payments, then retry from the certificate page. A failed charge leaves no payment behind, so a second try is safe. Keep the exam pass screen open until the certificate link appears.
Progress page drops a finished unit
Open the unit and confirm its test shows as submitted, not only answered. Progress counts submissions, and an answered test left unsent stays open. Resend the test, then reload the progress page.

Frequently Asked Questions
How do I enrol in a Mathesis course?
Create a free account, open the course page and press enrol when the course opens its list. The course then sits on your dashboard.
Does Mathesis charge for its courses?
Courses, tests and the final exam are free. Only the completion certificate carries a small fee, and it is free for the unemployed.
Where do I download my Mathesis certificate?
After you pass the final exam and complete the certificate step, the file appears on your course page for download.
Can I watch Mathesis lectures after the week ends?
Course videos stay open for enrolled students during the course run. Tests, though, close when their week ends.
What happens if I miss a Mathesis weekly test?
A missed weekly test counts as an unsubmitted unit on your progress page. The final exam still decides the completion mark.
Why does the Mathesis exam page show a timer?
The final exam runs against a set clock inside the browser. The timer starts when you open the exam and keeps running if you leave the page.
