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.

Mr. John O’Sullivan's grinds were incredibly helpful. The live classes were super engaging, and he explained everything clearly. If there was something we struggled with, we had access to class recordings, allowing us to replay them at our own pace, as often as needed. He was also quick to reply to any questions via email, which was great if you were too shy to ask in class. The notes were amazing and very comprehensive too.
