I agree with others who have commented. These days, age doesn’t really matter when it comes to continuing your education in whatever field. I’m back in school studying Korean and am the oldest at 40. The next oldest is 30, and the youngest is 23, I believe. The only main difference between going to school now and doing it before is that I don’t often hang out with my classmates after class.
I did my MFA in Creative Writing from 29 to 31. I was basically in the middle of the group. There were several people who were older, about my age now, and several people who were younger, the youngest of which was probably 23 also.
But as they say, it’s never too late, and these days, a lot of people don’t even finish their Bachelors until their mid 20s. The rules on all of this have changed with the times.
