Really good explanations! I loved how you made sure that everyone understood the concepts before you moved on and how you went through numerous examples, making sure that everyone was comfortable with the concepts and explaining the concepts to the rest of the class!

Justin was very patient during the entire session, willing to pause and wait for any learner if they had a question on the content. He also was super friendly at the beginning of the session, welcoming each learner into the session by name and making the entire session feel like an inviting and welcoming place to learn. Moreover, his teaching style is very adaptable to multiple learner's needs, and he is able to either speed up the pace or slow down the pace according to what the learners as a whole need to understand the material. He also prepares a variety of different practice problems so that his learners can make sure that they understand the material well and can apply it to different situations.

I learnt a lot yesterday. The series is now a highlight of my week now lol. I understand stuff a whole lot better now, and understanding the world around me gives me an ability to enjoy it better. Thanks for the session!
