Here is all you need to know about this course. I've been a .NET developer for about 4 years now. I don't have a ton of experience with Core. My new job I'm starting if a few days uses core so I wanted to find a course to brush up. I have about 20% hearing in one ear, and about 60% in the other ear. Listening to people with unfamiliar accents is very hard for me. I can hardly even understand people with British accents. I have purchased almost 200 courses on Udemy and almost all of them have native English speakers. I bought this course because it looked really good and it is. This course is SO good that I don't mind having to listen to sections 3-4 times to fully understand. The fact that I am pushing through the course without even being able to understand a good portion of it tells you how good it is. Don't even think twice, just buy it.
