Like many students talked to a lot of students are not hard, but could not find the feeling. One thing is undeniable, the same class in a classroom, a teacher is also teaching, learning different. The key question is, bring a sense of advice I can give is to bite the bullet, hold on, no knowledge will not. We will continue to share experiences of graphical programming, hoping to make a topic. If you find useful, give a point like it. Software covered include scratch3.0 (.sb3), Python, Kittenblock.
