there is stuff on the higher level course that isnt on the ordinary level course, also the stuff that is the same on both courses are to a much higher standard in HL irish. no matter if you're in 5th or 6th year its probably too late to move levels, plus, HL is hard, especially if you were in an OL class till now
im rubbish at irish barely work for it you can easily pass the subject by looking at a few notes before the exam honestly . i went into mocks with no study and still passed it just listen in class you will pick up words that you can use in your written exam
You aren't allowed to move up. Now that everybody has passed due to the situation with the orals, the Department of Education has made it very clear that Ordinary Level students won't be allowed to take advantage of the situation and switch to Higher Level.
