I currently go to a 7 sister’s and am majoring in math. I’m also a pre-med. I have completed almost all of the advanced math courses and it is next to impossible to take more advanced math because of scheduling conflicts and limited availability of courses in the college. I intend to pursue clinical medicine but would also like to keep the option of consulting open (which is partially why I’m majoring in math). Question is, is it worth trying to transfer to a uni where I can pursue higher level math courses, and have better network for finance/consulting since I may pursue it in the future? Thanks 
Also, am I at a disadvantage if I major in math as a pre-med ? I’ve been getting mostly negative opinions on my choice of major as a pre-med. 
I don’t think I’d enjoy majoring in anything else as much.
rule 1: follow your interests. If you enjoy math, do math.
rule 2: separate out the pieces. Guessing your scheduling conflicts relate to your pre-med lab classes? If so, your pre-med plan is getting in the way of your finance/consulting plan. Also, you headline with math, but the ‘better network’ reason slips in- that’s your finance/consulting plan again. A math major is popular in the finance/banking side- but so is an econ or business major (or biochem or physics for that matter), but completely unnecessary for consulting (McKinsey/Bain/etc). Go back to rule 1: follow your interests.
As for whether or not to transfer- what year are you?
Yes premed and math have scheduling conflicts.
Well I intended for math to be my segue into finance/consulting. I’m not interested in any other math related career. And much of consulting can be learned on the job, from what I’ve heard.
The disadvantage to transferring as a pre-med will the difficulty in obtaining strong LORs for your med school application. Universities that offer a committee letter for med school applications often will not write a committee letter unless the student has completed at least 2 full academic years at that university. Additionally, some med schools require and/or strongly recommend that transfer students obtain LORs from every undergrad school they have attended.
LORs are critical part of your med school application portfolio. A weak, wishy-washy, or indifferent LOR can tank your chances for a med school admission.
What year are you in school? If you’re a current freshman, then you have time to cultivate relationships with your professors to get those LORs and apply to med school during your senior year. If you’re a sophomore or later, you’ll need to postpone your application cycle until after graduation and take a gap year or two.
I know of one (science) professor here who will recommend me highly who I’ve been working with for almost a year now, and a math professor from the college I want to transfer to, who I’ve worked with before. I’d probably reclassify as a sophomore (this is my second year) if I were accepted to one of those universities, so I could avail of the advanced math courses offered there.
