Do you have any tricks to help someone who's taking an online algebra course?

I am so frustrated that I swear will never take another math course online. Most of it’s fairly straight forward and simple, but man, when you get stuck you STAY stuck because there is no one there to give you that little tweak that will suddenly make everything crystal clear. My teacher does answer my emails, but sometimes it takes a day. Being stuck is causing me to fall behind, and that’s not good.

If you’ve taken an online math course, what were your experiences? How do you compensate for this?
