Need a chemistry tutor for high school and exam prep

I’m looking for a patient chemistry tutor to help my teenager with GCSE-style topics and upcoming mock exams. We want a tutor who can explain concepts clearly, provide short practice quizzes, and tailor lessons to our schedule. We prefer a sessions-focused approach on stoichiometry, bonding, acid-base chemistry, and calculation methods. Ideally, the tutor can work online most weeks, with occasional in-person sessions if local. Must have experience with exam-style questions and be able to track progress and adjust the pace as needed.
