I personally didn't go to an art college myself. I'm actually a computer science major who decided to chose art as a profession. I took a short course on multimedia arts here but it didn't help me much. I was only able to improve my art skills drastically when I worked on the studio and doing some self-studying.
So regarding to your question, I can't actually say whether it's worth it or not. If you live in our country, I'd definitely say that it's absolutely not worth it because most art schools here tend to focus more on business rather than actually teaching students and their tuition fees are absolutely outrageous. Most of the artists here on Philippines are freelancers since there isn't that many studios here to get work and most of them didn't really go to an art college.
I have to apologize if I wasn't able to give you a satisfying answer.
