Deereret,
You'll just have to keep at it. You've already made progress from the last time you posted about it, so....

Remember too, that with an instructor you'll get immediate, verbal input when you're making a mistake, and advice on how to correct for it.

When trying to learn on your own, even with a Sim, you can keep repeating the same mistakes without even knowing you're doing it.

Good luck,
Dennis-
