I'm cooked!

Hey guys, I'm a complete newbie to 3D modeling here...

I'm having a lot of trouble modeling a Game Boy Classic. I was following the PIXXO 3D tutorial until I realized it only models the front. I went to check out Chrismartinartist's tutorial, but I started having trouble right away, so I gave up.

Is there anywhere other than YouTube where I can access simple tutorials to help me create a good final project? It's for a school project.

Thanks in advance!
