Hi all,

I am interested in pursuing a PhD in Statistics. Unfortunately, my undergraduate degree is Linguistics and I have few math credentials. I recently took (and aced) a real analysis course at a local university, but it was pricey, and I'm hoping there might be a less expensive way to certify my mathematical knowledge and abilities. In particular, I am wondering if there is any possibility of taking exams offered by some reputable society that cover material in undergraduate-level mathematics. Something sort of like AP exams, but for more advanced subjects.

I have a 740 on the subject test and intend to take it again (I am currently learning about abstract algebra and some of my other weak spots); however, a multiple-choice test has obvious limitations. I am not eligible to take the Putnam exam since I already graduated. Beyond those, I really can't find anything that might suit my purposes.

Can anyone think of any math exams that might be helpful? Thanks in advance!
