Should I drop out?

Hello, I am a student major in Computer Engineering and I am in 3rd year now. I have been following Hackernews for a long time because I am interested in technology and start up. I really love learning practical technologies which I can see their result immediately. Gradually, what I am self-learning are divergent from what I am taught in my university (I am self-learning iOS game development, Node.js... and I think you have already known what our university is teaching us). This makes me headache because my time is limited, I feel I cannot do both well. Therefore, I consider drop out and focus on self-learning. Does anyone have the same experience? Can you share what you did then? Thank you.
