This set theory course was really helpful in understanding the concepts of terms. Of course, you won't learn everything in one study, but this course helps you understand the flow and learn what to study later when needed. The time is just right, the lecture tension is good, and the best part is that there are subtitles so you can see unfamiliar terms. However, I think I'll have to keep a textbook next to me to solidify the concepts the teacher mentioned. If there's a textbook that I can easily review or study, I'd appreciate it if you could recommend one. I'm also looking forward to the next linear algebra. Teacher! Thank you for the great course.
