Our Verdict

This top-rated C# Intermediate course by Mosh is an excellent resource to enhance your understanding of classes, interfaces, and OOP. Though it features superb instructional style, some students face difficulty in the final section dealing with interfaces and unit testing. Furthermore, there's room for improvement with more concentration on quizzes and additional exercises targeting various concepts. With timely updates to cover recent language changes, this course can be a 5-star offering that prepares learners for advanced C# programming topics.
