So I’m pursuing a Bachelor of Science in Chemical Engineering, but it also says Material Science along with it. (I’m a freshman, classes start soon) Additionally, we have to choose a concentration (going to pick biological engineering).
What’s my degree going to say specifically? Also any ideas on job growth/outlook, or salary?
Thanks!!

Note that the pay cited there is median, not entry-level.
You will have to ask your university how the degree will be printed, because they are the ones who set that. There isn’t a national standard or anything.
Also, none of us can really tell you anything about job growth or salary. There are the broad guidelines put out by the BLS in the OOH, and none of us really have the kind of data to refute it.
Your university is the one who decides what your diploma will say. Usually it just says your major(s), but not minors or other special tracks. Employers sometimes do not really care about what your degree is actually in, they just care that you can do the work. This is especially true with CS - they care about how you perform in a coding interview, not so much whether or not you majored in CS.
