<p>computer sicence or physics, I'm not sure which field I want to go after undergraduate, so I'm studying pure math as my undergraduate degree and also I took some physics class and computer science class as well.</p>
<p>In this case, can I appy to graduate physics or computer science in future </p>
<p>Same answer as the ones you’ve gotten in the MIT forum :-)</p>
<p>In short, yes. Math is a good base for either.</p>
<p>I think you should take a look at the web sites of schools that you might be interested in, for grad school. Often, they will have a list of core courses (physics) or courses/experience/knowledge (computer science) that they want entering grad students to have. If you have that, then your major will not make a difference, and advanced math could be a plus, especially for physics. If you are a couple of classes short of their list, then your odds of admission will depend on the quality of the rest of your qualifications compared to their overall grad applicant pool.</p>
