What the students say
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. Lillian 2024
