Has anyone else found university grading systems a little confusing, especially when moving between different countries or institutions?

I was recently looking into how grades are assessed in Ireland and noticed that students may need to understand percentage ranges, grade classifications, and how individual assignments contribute to their overall results. The college grading system ireland can be particularly useful to understand for international students who are unfamiliar with how academic performance is evaluated.

I think knowing the grading structure early can also help students set realistic targets for essays, reports, presentations, and other coursework. It may even make it easier to understand how much effort is needed to improve an overall module grade.

For those studying in Ireland, how did you find the grading system when you first started? Was it easy to understand, or did you need guidance from your university or other students?
