Chemistry tutoring from an Imperial biochemistry student

I am Biochemistry undergraduate at Imperial College London. I am very understanding of students who struggle to grasp concepts at GCSE level, as I know chemistry can be very overwhelming at times when it isn't explained clearly. I have prior experience tutoring chemistry at GCSE level and acheived a grade 9 myself.
I believe the best way to teach is to ensure my students fully understand the core concepts first before moving on to mastering exam technique, as being confident in the subject matter is the key to mastering chemistry.
