I’m seeking a patient chemistry tutor to help my teenager with high school chemistry. The lessons should cover topics such as stoichiometry, chemical reactions, and basic organic chemistry, with a focus on problem-solving and exam preparation. Ideally, the tutor can explain concepts clearly, provide practice worksheets, and adapt to a pace that suits my child. We’d prefer online sessions, but in-person near London could work if convenient. Availability during weekday evenings or weekend afternoons would be great. Please share references or a short teaching approach when replying.
