It's up to you. If you really make up your mind this time and your grades are not too bad, then you can choose to repeat. In fact, I can tell you that there is not much difference between most people's repetition and 1 year. Sometimes it will go backwards, because the pressure of repeating a year is particularly great. You must have enough psychological quality and determination to make progress. The tuition in this university is a bit expensive, but it depends on what you want. If you want a diploma, it is worth it. If you don't want that diploma, you can change to another school, or a school with lower tuition.
