Web sites for training on 2002? need help

I have been able to so some simple stuff however it seems that a lot of
things don't work all the time and there are at least two or three ways to
do everything. I find the help menu of little help in what to click on for
a simple icon like trim/extend/break etc.

Can someone please post any good sites easy simple to learn a little here
and there at a time.

For instance I find just drawing a circle with the circle icon not easy
especially when you try to move it.

This seems like a good site, will try to spend some time here.

Thanks,

Gary
