Students at Trinity College, Dublin have occupied the campus dining hall.
They've done so in protest against the new €450 fee Trinity will charge students to repeat exams.
At the end of February, the college's board passed a vote to introduce the charge, which will stay at €450 regardless of the number of exams a student has to sit.
The Trinity College Students' Union say they can no longer stand for the "commercialisation of students".
A rally took place this lunchtime, and got plenty of support.
