I learned last year how to work Maya, and these videos help me make my final project. It teaches you how to make a 3D model of a room and how to do it. The person who is talking has a monotone and explains it really well. He is very helpful and easy to understand.
Codecademy was the main factor that helped me throughout the years in the I.T. Campus. It taught me how to make my own personal website. These tutorials are very useful and helps you understand what codecademy is all abou and how to use it.
One of the lessons that I learned in I.T. was the 12 principals of animation. It was very useful in teaching me how to make a cartoon video if I ever made one, and how it could be deemed "good" or "successful". You will see these 12 principals in a lot of cartoons and movies!
