A disappointing lecture in many ways.
There are no issues with the curriculum itself, but the way the lecture is delivered is somewhat unfriendly.
First, there is little effort to help students understand mathematical notation or to explain things in simpler terms. After a brief, simple introduction, the instructor immediately proceeds with the content using that notation as if it's common knowledge. It feels as though several years of middle and high school mathematics have been compressed into just a few sentences. Because of this, I had to spend a significant amount of time searching externally or using AI to understand things whenever I got stuck.
I could somehow accept and move past this by telling myself it was due to my own lack of mathematical knowledge.
However, there is something even more disappointing. When you pay for a lecture, it is only natural to expect the lecture materials to be properly displayed on the screen. It is difficult to understand why the instructor occasionally shows their Instagram or lecture materials that were not provided in advance. Watching the instructor scroll through their own e-book or blog while reading explanations was the height of frustration.
At one point in the lecture, the instructor says:
'If you look at the book, I've defined the function below.'
Naturally, the students do not have the instructor's Instagram handle or their e-book. Why should I have to pause the video and read through these things one by one?
The lecture flows so roughly that it feels more like the information is being scattered rather than taught.
While the direction of the knowledge they intended to convey was good, I believe the lecture was poorly prepared.
