Is the education percentage important for admission to Ireland, and will low marks be a problem for a Master's/Bachelor's?

Yes, your academic percentage is important for admission to Irish universities. Most master's programs expect at least 60% in your bachelor’s degree, but requirements can vary by university and course.

If your marks are below the standard cutoff, it may limit your direct admission options. Some universities may offer alternative pathways, like foundation or pre-master’s programs. Strong work experience, a compelling statement of purpose, and high English proficiency scores can help strengthen your application if your marks are low.
