Firmed a degree I don't want anymore!

Email both uni's and see if they can change your course?

Think about this properly though, its the next few years of your life ultimately and you can always pick up Japanese at a later stage of life.

All the best.

Well, remember that you don't have to do Japanese at uni to study it.

I mean, I love ancient history, but it's a difficult course and the career prospects are limited. Instead, I can do something else I'm better at and get a good job. And with that money I can still buy books about ancient history and go to museums etc. I don't have to give it up.

Just because you're interested in something doesn't mean you have to devote your life to it. We can all have hobbies.

Not saying don't do it. If you've decided you hate architecture and have a burning passion to work in a field related to Japanese language, then by all means. But if you have a promising career planned out that you were happy enough to do, it seems rash to change if this is only a passing fancy(because remember, this is years out your life we're talking, and interests often come and go),

Just think about it. Don't act impulsively because you've suddenly found something new and exciting. Everytime I leaf through a prospectus I find some new fanscinating course and think "oh, I wish I was doing that instead!" It's natural. What you need to figure out if this is just one of those "ooh!" moments, or a legitimate realisation that you're doing the wrong thing. If you did architecture, would you be really miserable? Or is the grass just greener on the other side?

Good luck!
