What is the difference between a B.Sci and a B. Arts&Science?

If you are majoring in microbiology and immunology, you’ll want a BS, not a BA, for two reasons.

1) Most BA programs skimp on some of the harder science. For Chemistry BAs (the half I have experience with), usually this means a reduced amount of physics and physical chemistry. Yes, you could take those classes anyway – but you might as well get your BS at the same time.

2) Your future grad schools/employers do not want to see a BA on your transcript if you are intending to work in a hard science field. They’d much rather see a BS who has taken extra humanities classes (which is what I did) and who participated in extracurriculars. BA screams laziness (even though it isn’t necessarily true) to potential employers/recruiters.

If you plan on going into education, BA is the way to go, but if you want a hard science career, don’t cheat yourself out of the more difficult classes. Definitely add on some extra humanities, classes, though. Your school might even have an honors program.

[ETA]

Sorry about the misunderstanding. From what I gather, BAS (Bachelor of Arts and Sciences) is for people who complete two full majors (usually one in an art subject and one in a science subject) and get one degree. I didn’t realize this was an option for combined microbiology and immunology, since neither is an “art” major. I would suggest going BS in both rather than combined because, honestly, it will still look better for you to take full loads in each. If, however, that’s altogether too much work, perhaps go for the “A” in the lesser important of the two and the “S” in the more important.

In my case the difference in my gettting a Bachelor of Science (B.S.) and failing to get a Bachelor of Arts (B.A.) was the fact that I failed to complete a foreign language requirement. That was the only difference in the two degrees for myself and a few people I know. Not certain, but I think the exact requirements may vary by school or country(?).

I have a BSEE and had to have 144 credit hours to get it. so I had to average 18 credit hours per semester. I think the BA’s were a little less, 16 credit hours per semester. so there was a little more studying to do. This was about 40 years ago so maybe someone can bring it up to date if that has changed.

This was at the University of New Hampshire in Durham, NH. It was an accredited university.
