Hi! I'm currently an undergrad CSD major and I was wondering would you say it was a good idea to double major in psychology or minor in psychology?
Double majoring never hurts–and it diversifies your application. My only piece of advice would be to make sure that you are not overloading yourself. You CSD grades are one of the most important things to apply to grad school. If you can keep those up to a high standard, you should be good.
