Putting all essentials aside, is a degree in both pure math and physics required? I am thinking of reducing the number of majors I have to just a minor in math and a BS in physics. Mainly because I had to retake some math classes and I do not think I will finish my degree in math at the same time I would finish my degree in physics. Is it just okay to major in physics and minor in pure math in I want to study topics in General relativity in grad school? Or should I continue with my degree in both Pure math and physics. I have consider the option of using MIT courseware site to teach myself pure math if I decided not to get a full degree in pure math. Would that be a good alternative to choosing to a degree in pure math.
