Hi,
Thanks for your comments we appreciate the feedback. We'll definitely pass it on to our instructors and pay more attention to this in the future.

It is our intention that you should understand why you're doing something when you're watching our tutorials, rather than just follow along and copying what's happening on the screen without actually learning something that you can apply later when you're working on your own projects. So we agree with you and we'll try to exercise better quality control.

I hope you're enjoying the rest of the tutorial and finding it useful.
