Love your videos, and really really appreciate the effort, detail, and above all, your expertise in these TA videos that you make, basically for free for everyone to watch.
Please ignore the idiots who do not understand the concept of gratitude.
Keep up the good work.

I really wish I have time to learn more about TA, but preparing for an exam at the moment. I hope to show you later in the year, that I have been doing my homework too!
