Reviews of professor Kostiantyn Tolmachov

Rating: 5.0/5, difficulty: 4.0/5
This guy is absolutely hilarious and endearing to watch. He gets very excited about math which is always nice to see. He explains everything very clearly, and will reopen TopHat for everyone. Highly recommend taking a class with him.

The guy is pretty young and super passionate about math. He's not the best at teaching, he mumbles here and there, however, if you ask him to repeat/clarify something, he gladly will. The course itself is pretty challenging; make sure to read the chapter and do the homework beforehand to get a better understanding from the lecture. Great guy :)

Don't be fooled by his youthful appearance, he's really good at teaching and is quite humorous. He doesn't spoon-feed you. he'd give you a question, let you have a go at it, give you a clue, let you go at it again then go through the entire question and will explain everything clearly.
