19yo gap year student (going on to study BSc Geography) teaching: KS1 KS2 KS3 KS4 biology

Sammy is my sister who is in the year above me at school, through GCSEs she helped me understand topics and concepts which I was having trouble with, walking me through questions, and gave me exam and revision advice that without which I wouldn’t have been able to achieve the grades I did. I went from getting 30-50% in yr 9 to getting 7 9’s at GCSEs thanks to her help and the time she put in to get me back on track. For my first year of a levels she has continued to help explain anything I couldn’t understand and and has enforced the importance of keeping on top of work and revision as the year goes on, thanks to her I’m now going into year 13 confident that I can get the grades I need in a levels (including an A in biology)
