You are ignoring the things I told you last time.  As I said, forget about
the line going off the page, forget about C2 for now, and concentrate on
just what R2 and D3 do.  There is a reason I ask specific questions in a
specific order.  If you want me to continue with this you have to at least
answer the questions I asked before looking around trying to figure out
other things.  Since you aren't really replying to my last message, I don't
remember exactly where we left things.  You aren't making it easy for me to
help you.  I said that once before, so this time I'm not going to quit here.

I'm sorry Olin.  I'm really trying. Please don't give up on me as long as I try my best.  I think you are a great teacher, and forgive me for trying your patience.

Did you mean R2 and D2 or R2 and D3?

This is just new to me. I don't know which lines and components to follow. I was trying to be logical, but didn't succeed.

Am I on the right track to try to see in which direction the current flows?

Kindest regards,
Lindy
