I'm a .NET developer who is new to Spring. I thought I'd be able to follow along well with the course since I've been using .NET MVC, but Spring itself is unfamiliar, so it's a bit challenging. (I think it's even harder because this is my first time using IntelliJ too.) I think people who are just starting development or trying Spring for the first time will probably take time to understand it like me. However, I think this is a course with so much to learn, including project structure and test implementation. I think I'll need to go through it several times after completing it. I'll keep at it steadily without losing motivation. Thank you for the great course.
