Dr. Sarah Mitchell

Dr. Sarah Mitchell's profile lists Oxford PhD credentials and a specialism in a-level chemistry & biology specialist. Students can request one-to-one support in A-Level Chemistry, A-Level Biology, IGCSE Chemistry, IGCSE Biology and IGCSE Science, with teaching matched to the relevant A-Level and IGCSE course requirements.

Lessons follow the Combo Tutors diagnostic-first process. The tutor reviews current work, identifies the concepts or exam skills holding the grade back, and uses those findings to set the next lesson priorities instead of restarting the whole syllabus.

Students can expect live explanation, guided practice and targeted questions linked to their course. Progress is reviewed through completed work and recurring academic priorities, while families can request a different match if the teaching fit is not right.
