They might annoy you, but its never too late. A lady who was in her 90's graduated from college a couple of weeks ago and it was in the news! You probably won't look any older than a lot of the kids there, and there are probably more people your age than you think because a lot of people take a couple of years off before going to college.
Absolutely not!! 25 can sometimes still pass for 21 or younger! I've worked with students that started a bachelor's degree at 60! You will fit right in - especially in graduate school. You *might* want to check out the schools first though. Sometimes those 18-20 y/o crowd can get pretty biggoted, but unless you look like a *really* old 25 y/o, they might not even notice... except that you might notice how immature they can be...
25 is not old at all. I guess you didn't see the article of the woman who was like 92 or so and went back to school for her Bachelor's. There is never any limit to age on getting an education. I have been in classes with people from 18 to 62.
No, your never too old for college! I am 25 and still working towards my associates. I changed my major a few times but you are never too old. The good thing now is that you have learned and will do your best to get it done.
Absolutely not!! An 83 year old woman just graduated from college not to long ago.
You will find that their are a lot of people you age that are still in school. Don't let the though of being with college kids hold you back from getting your education.
