Naomi Rockler-Gladen over at Suite101 has a good article up at the moment on things to consider when you think about changing your major.

Everybody does it. Most students do it a couple of times. Naomi has some SAGE words to offer:

Have you come to truly detest your major? If so, seriously consider changing it. You're not going to get much out of your education if you're miserable. Alternately, it's common for students to develop new interests after they come to college, so you may discover a major you love. if so, this may be the direction for you.

If you're switching from psychology to sociology or from English Lit to Drama, you may not encounter many problems.

On the other hand, if you've invested two years of your college career in dance or French and you've now decided you'd rather major in equine studies or computer engineering, that might be a bigger leap...

Naomi looks at a number of issues you need to consider - like whether you can still graduate on time and how you go about evaluating the job market for your new major.
