I also did an Irish course at the Study Hub which I found very helpful.
I would highly recommend the Study Hub. I just completed the leaving Cert this year and I am delighted with my results. Breda was always very encouraging and helpful. Was always there to motivate us and it was a very relaxed atmosphere with no distractions. This was important to me as I found it hard to study at home.
