Hi. I am a Junior now and have to decide what major to declare. It is very clear in my mind that I will major Physics but I also have it in my mind to double major Math. But, here comes the problem. I feel that I have to study more math in order to do better and go higher in Physics. That's essecially why I started thinking about double majoring the math. So I've got it all figured out what my schedule should looks like If I doulbe major Math. It turned out that I might have to stay one more year or at least one more semester(or two quarters). Is it really worth it? I heard some people saying that it will help to look good for my graduate school application if I have Math as my second major. But I also heard some people saying that it looks really bad if I stay as undergrad more than the regular two years. So I am totally lost at this point. I am already turning 22 years old now. So, if there is anyone who's already in Graduate program in Physics or anybody who knows much about the Graduate selection process, I beg your advise based on my concerns!
