It might be worth finding a tutor in stats then. It may have been a bad prof as well. I withdrew from Stats my first go because the prof was horrible, but with another prof it was OK. I think the important thing to remember in Stats is: how many variables do I have available, is it comparison or causation, how many variables can I manipulate. Other than the first class, most of the time you plug it into a computer; the trick is knowing what test you are using. I did one experiment where I did not find significance in a t-test, but did in an ANOVA. Using the right test really helped.

You probably didn't need all that much info though. As for the classes, I go for which classes I will enjoy most, with a slight preference to higher level courses. If I am not interested in the material, it will be difficult to get engaged and to do the work and studying.
