As the title explains, I am soon going to attend college and I would like some advice one can give for an upcoming physics/mathematics major. 1)What are some things/extracurricular activities/programs/etc. that you recommend a physics student do in his undergraduate years to maximize both their learning experience and chances for graduate school (especially the latter). 2) What societies/clubs are good for a physics student to participate in to assist with question #1. 3) What would you advise for questions #1 and #2 for a mathematics student (I am currently a bit undecided between the two.) All responses will be greatly appreciated!
