In Ireland, a grade of above 85% on exams is generally considered very good. It indicates that the student has demonstrated a high level of knowledge and understanding of the subject matter being assessed. However, the specific interpretation of exam grades can vary depending on the grading system used by the school or educational institution.  It's important to keep in mind that exam grades are just one aspect of a student's academic performance and should be considered in conjunction with other factors such as attendance, participation, and overall engagement with the subject matter.
