@jasondyong629 ,
Sorry to hear of your frustrations.
The older courses here at CG Cookie are still relevant in teaching the fundamentals of 3D modeling using Blender.
Blenders UI has changed considerably over the past few years, causing the frustrations like you are experiencing.
More accurately, Blender is changing on a daily basis.
The older courses will at some point in the future be replaced with new courses using the latest version of Blender, but this takes time.
From start to finish, preparation and planning to recording and editing through to release can take several months per course.
The tutors are working on new courses as we speak, in the meantime the older courses will remain.
Better something than nothing, right?
My suggestion is to visit blender.org and download the version of Blender used in the course from the Previous Versions of Blender page.
That’s what is so great about Blender, its free, with all previous versions still available and yours to keep forever.
Alternatively, you may want to familiarise yourself with Blender, with the Build and Animate a Low Poly Rocket course, and of course the Blender Basics is an ideal starting point.
Lastly, there is an awesome community hear at CG Cookie, Ask and you shall receive.
Have a cookie and carry on.
Happy Blending
