Do you hope to become a psychologist?
Is that part of a Bachelor of Arts degree, or do you have to be doing Science to major in psychology in North America?
In Australia you can major in psychology through either a BA or BSc. I don't know how things are up that way, but down here becoming a psychologist is really competitive. You have to get solid marks in your undergrad to make honours and then from what I have been told you need to do even better in honours to get into Masters.
I am doing a little bit of psychology as part of my degree, it is a really fascinating field. Numbers aren't my strong suit though, there is no way I could maintain an 80%+ average through the statistics classes, so I don't intend to pursue it as a major.
Best of luck with it mate. I am sure that if it is what you want to do, you will find the motivation to do really well.
