            I started learning programming w/ Mosh 4 years ago with his C# & .NET courses. Thanks to those I landed my first job. Then, I continued to learn from his materials and made the jump from Jr. to Ssr. and then to Sr. Software Engineer (my salary went 10x from my first job). Now, 4 years later I continue to learn with his excellent courses.

            Mosh doesn't fail to leave out important details. You can tell that Mosh has put a lot of thought into creating these courses. His professional and personal experience drives these courses to be thoughtful and outstanding.

            The best courses I’ve participated so far. Mosh has a unique teaching ability. His lectures are fun and engaging. The visuals are great. Relatively dificult concepts are explained with simple words. Whenever any one asks for a programming course I recommend Mosh Hamedani, and only him. Other courses I’ve had were at best mediocre.


            I love how every part of the course is broken down very well that even beginners can understand it and not feel overwhelmed, confused or carried away. Also how the lessons/course is in sections, one can go back to a particular section for review if need be especially when working on the exercises.

            I found this course to be complete and very clear and easy to follow. Mosh is very good at explaining, it feels like a friend talking to you very naturally, and the course is very entertaining. And it comes at an amazing value! I definitely recommend it!

            This is my second course from Mosh and it is great as well, The way he explains little details (how and why's) is very helpful and builds a solid base of understanding the code. Great instructor!
