Thank you for the 5-star rating and kind words~ I go into more detail about things that colleges can't teach. You might feel that way because colleges teach mostly theories. However, college classes are really important because you learn academic content that you can't learn outside of college. It's fun to apply the theories you learn in college classes to practice and experiment~ My classes cover experiments and implementations that college classes can't cover, so you can think of them as an extension of that :) Then I hope you enjoy the remaining lectures! Thank you.
