Reviews of professor Ray Han

Rating: 5.0/5, difficulty: 3.0/5
Ray was an inspirational teacher when I took his Intro to SQL class at UCLA Extension. His background educationally and vocationally speaks for itself, and translates to real life experience and examples in class. Most notably, he wants to see his students succeed outside the class by teaching courses to jumpstart careers into the tech field.

Professor Han makes himself available outside of class for any questions or general guidance. He has a wide breadth of experience which is great for a bird's-eye view of technology, yet he can drill down to specifics as well. He has a charismatic personality and keeps the class engaged with the material.

He always tries to encourage his student to learn more and grow on their career path. His support and teaching helped me on my path to my master's degree. I see Ray as both an instructor and a mentor.
