LOL! I was lucky because I already studied French and a little German. "ж" is like the French "j". Just put your tongue in the middle of your mouth and don't let it touch the top of your mouth then pronounce "j".
Oh, and "р" is like a trilled "r" but at the back of the mouth.It's fun to learn. Just do what I did and learn a few letters each day till you know them all.
Just one problem. Now when I speak English it sounds like I have a Russian accent, LOL!
