I recently just transfered to a new school majoring in Physics and Astronomy. I plan on continuing on to Astronomy grad school. I have taken 2 CS classes in the past and only need 3 more for the minor. It also happens that this school happens to have a very good CS department(top 20). Is getting a CS minor something worth doing, will it help me in my future work as an astrophysicist or will getting the minor amount to nothing more than words on a piece of paper?
