Our students love us

I decided to take up Chemistry last April as an outside school subject two months before the exam as I needed a H4 for course requirements. With John’s expert tuition I achieved a H3 in the leaving cert exam. He was exam-focused in his approach. He explained the difficult concepts and experiments clearly. This was particularly impressive considering all our grinds were done over zoom. He has a clear passion for the subject and a real interest in his students. My result would not have been possible without him.
Mr. O Sullivan’s Chemistry exam had a great balance of questions with enough challenging ones to keep me studying and not to start relaxing but also with some manageable ones to boost my confidence and reassure me I was on the right path.
The grinds were really helpful and worthwhile. Once I started the grinds I was able to pinpoint and focus on the difficult parts of the course which benefitted me a lot. I felt I was well prepared for my exam which definitely helped relieve a lot of stress
The pre-exam gave me an insight into what areas of the course I needed to focus on and it was a great to experience doing a full Leaving Cert style Paper.
