Chemistry tutor providing lessons to students from all levels

I have a PhD in chemistry and over 5 years of tutoring experience, having tutored mostly secondary school and university students. My tutoring approach depends on the student's needs - I can either go through theory, or solve past exam/tutorial questions, explaining in depth the chemistry concepts needed to answer each question. Therefore, by the end of each session the student should be able to solve any question related to those specific concepts.
