I cant follow along because the selection doesn't work in the same way?
Hmm, I don't think the selection methods have ever changed, apart from the old right click select is now left click select by default, but you can change it if you wanted to.
What is it specifically you are having trouble with?
Have a read of these, they might help you overcome the doubts you may have with the older version.
