I am a developer job seeker with a non-major background. If I had known about Younghan’s spring lectures earlier, I don’t think I would have spent a month in the dark, depressed, and hopeless. I was lost and worried because I didn’t know properly. I am taking the classes according to the roadmap, and the darkness is disappearing from my face as each part that I was stuck on is resolved. You asked me to give feedback on the class in the course review… I can only say thank you.
