If you’ve decided to go to grad school but aren’t sure which one is right for you (or where to apply), it can be really useful to ask people who are in those programs (or were recently) about their experiences. Start with people you know (friends or professors, for example), but it’s also okay to reach out to fellow alumni from your undergrad, or even cold email grad students from the math department website at schools you’re interested in — just keep your initial email short (“Dear so and so, I’m so and so, interested in getting a math PhD at such-and-such, would it be okay if I ask you some questions about your experience?”) and be prepared to take no or silence for an answer. A few people will be happy to help out and you can learn a lot from them.

Here are some things you can ask people about their grad school experiences:

You also might want to think about what matters to you personally in grad school: there are the academic and professional things I’ve already mentioned, but there’s also: how much would they be paying you (it’s okay that this matters — grad school is much more like a job than undergrad!), is it in a location you want to live in, how easy would it be to travel (to conferences or to visit loved ones), are there amenities nearby that are important to you (and would you have a way to get to them), and so on? These will matter different amounts to different people, but it’s important to think of grad school both as a stepping stone to future possibilities AND as years of your life that you want to be a good experience in itself.
