If you (or your child) are struggling with your chemistry at a school or university level. I am more than willing to offer my service as a tutor. I am a student entering his Masters year in a Chemistry degree at the University of Edinburgh. I have lab and research experience in both English and German. I can help and we will take it as slow or fast as you like. You can learn topics and concepts like stoichiometry, reaction mechanisms, kinetics or thermodynamics.
