Currently an S6 student nearly leaving school and looking to build experience in tutoring

I have sat my national 5/GCSE chemistry exam last year and successfully scored an A in it. I have also studied Higher Chemistry and sat my exam in May but result is still pending. Currently at 6th year I am also studying Advanced Higher/A levels chemistry. I have had experience before in a Techfest event where I demonstrated a science experiment to groups of pupil of different ages and that has helped me develop communication between a teacher and a pupil as well increased my confidence and ability to pass on information to pupil.
