    As an engineering undergrad, I'm impressed with the passion and the effort that you put into your lectures, as well as the sequential procedure that you take and the tiny details that you consider. Keep it up Sir!

    "I would be (upset) unless I gave you at least, like, two examples of how to actually use this."
    That right there is the sign of a good lecturer.

    Just to add : thanks very much for the commitment and efforts at making math , calculus , etc easier, more accessible, interesting and fun .
    I avoided it in lower secondary,struggled but failed it in high school,struggled through it in college , but now thanks to instructors like you, I'm learning more math , better , and learning it easier .
    Math is still very material and relevant to me and I need to have a stronger foundation and better recall -because I'm continuing in my lifelong learning in social science and more post-graduate programs.
    Thanks again.

    So i really enjoy math, and i'm currently working on my bachelors of education to become a math teacher (hopefully calc), and with you as my teacher I have aced calc 2 and i'm about to ace calc 3, so thank you so much for that, but that's not the reason for my comment.
    I do not attend my university lecture and instead follow along with your videos playing at 2X speed. Works just fine for me, and i really love how you get super into the "main point" portions of lecture at the end of a long description. Well, because of this enthusiasm, at 26:55, you're about to finish the intro to double integrals, and you get really excited and make a comment on how squeaky your voice got, and wow was it hilarious at double the speed. Just wanted to say that because i had to pause for a while so i could stop laughing and pay attention again.
    You're the man Mr. Leonard, I really appreciate all these and you're definitely someone i look up to when imagining my future teaching career.
