Detailed, comprehensive and thorough lessons, courses on various topics  in Chemistry.
If you need preparations for tests, exams (either High school, Undergraduate or Graduate level), Chemistry Olympiads, AP or IB  examinations or you simply love science and want to deepen your skills  and knowledge I am ready to share everything I have - experience, words,  tricks in order to achieve your goal.
I am a PhD student and during my High School days and undergraduate  and graduate studies, I spent many hours on various seminars.  I was a tutor at Petnica Science Center (Petnica, Serbia);  prepared one  generation of High school students for Chemistry Olympiad who performed  well at the State Olympiad and so far hold many private lessons in  Chemistry, in person.
During lessons, I use visual materials if needed, 3D models, problems from  real exams, Olympiads.  In my opinion, Chemistry, and science in general,  are more about understanding the concepts and that is on what I insist, so  the students can use them in solving the problems.
If you have any questions, I will be glad to answer them.
