What our students say 

I attended John O Sullivan’s weekly chemistry grinds, I was a H5/6 chemistry student and received a H2 in the Leaving Cert. This is mainly down to John’s help, would highly recommend the course.

John is a great teacher who will no doubt help you achieve your potential in Leaving Cert chemistry! His notes and classes were invaluable to me on my path to achieve a H1.
