What Do You Think - Is It Better To Study An Arts Or Science Subject At University?

are you really passionate about something worth your study time?? Keep employment aside, what are your interests? Then consider your future employment (unless you are someone blessed by fortune).
I dont think that asking a bunch of folks for career advice without them knowing anything about you.

Math. If you like and/or are good at math do science. Otherwise arts.

Choose the course of study which you can get the best grades in and can enjoy the most. Unless you are rather specifically studying something (e. g. you want to be a doctor or an engineer), the subject of most Bachelor's degrees doesn't matter, even when you are looking to go to graduate school.

For medicine, it helps to have a background in Biology, Chemistry, or the like, but I knew a guy with a BA in Economics who went to medical school. It's not impossible, although you need to take the prerequisites either way. Same thing with engineering; if you want an MS in, say, civil engineering, you will need a lot of background courses but there's no law saying those can't be a part of a minor or a double major as you get a Bachelor's in something different.

A friend was a very good hydraulics engineer working for mcdonall Dougls and was a team leader in a number of militry jets. He got the shits of being attached to one or two career length projects working on same things. SOO, He became a Urologist. Sorta the same stuff

I got all my advanced degrees in a science but also did a BFA in studio art. Interests rule. Money will follow.

That's funny, farmerman.

Don't do science if you are from the US, Michael. They are still in the stone age as regards science.
