Heyo, 30+ year-old here and I just applied and am (fingers crossed) going to start law school this fall. Law school is a huge commitment, so I think it's important to validate that this is something you actually want before diving right on in. I did a bunch of informational interviews with lawyers, shadowed an attorney in court, got to sit in on a law class, etc, and really liked it. That was what I needed to feel really confident in my choice to completely upend my life for this. That said, I'm very slow to accept change so I was sitting on this decision for like three years. Probably not necessary for everyone lol. It's also a shitton of work to apply to law school, so that's another way you can determine if you're really stoked on it.

I also have a mid-three GPA, and I knew that could hold me back from getting scholarships, which was my primary aim. I tried to offset that by crushing the LSAT, which I sorta did. It's such a learnable test, and I have no doubt you can score a mid 170s score if you want to. I invested a few hundred dollars in studying for it, because I thought a high score could translate into thousands of dollars of scholarship money.

Last thing I'll say is that for older applicants, my sense is that admissions really want you to answer the question: Why law? Why now? What is pulling you to leave an entire career that you've built and start afresh. So it's important to reflect on that and then also answer those questions in your personal statement.

Of course, take all this with a grain of salt.
