After school help: helping students with all their subjects from all over the world!

I am a dental surgeon and I reached here through many difficulties. I couldn't find the help I needed while studying in school nor in Uni, and I would like to use all the skills and knowledge I have to help students learn and most importantly, teach them how they can learn on their own and maybe even use technology correctly. All while finishing their studies with them daily and preparing them for their exams or whatever challenges they have.
