score improve- GCSE/A-level/IB chemistry Tutoring with 200h experience

I started tutoring when I was doing my Chemistry degree, till now, I have over 200 hours of experience in tutoring GCSE/A-level/IB chemistry and 80% of my students have improved their scores by more than 30%. I have research experience in the chemical industry, also went through the exams myself when I was a student, I can understand chemistry in a practical aspect and accurately interpret the exam question type and help the student improve their score. Since chemistry involves many abstract concepts and complicated chemical formulas, I usually share my screen from IPad during the online lesson, so I can draw/note the chemical structures to provide a more straightforward explanation. My teaching style tends to be encouraging, I believe that the reason why most students temporarily cannot catch up with their studies is the misunderstanding of certain concepts. I would like to create a safe teaching environment for students to ask any questions they want and avoid further misunderstandings, rebuilding their interest in chemistry.
