I think you are discovering what has been talked about on these boards, how hard it is to balance music (I assume a performance degree) with another degree, the amount of time you need to spend on music is going to be significant, and then you have the other courses you will need to take, and it is a lot. Here are some questions for you:
1)Why are you doing a double degree? Are you doing it because the second degree is needed because music is so chancy as a career (either yourself or your parents pushing this)? Or are you doing a second degree because you need/want to have the academic courses in your life, you would be bored with music, etc… if you are doing it as a hedge against music being difficult to make a career out of, you likely are hurting yourself if you are struggling to balance music with the academics. What it sounds like is both your academics and your music are hurting, and you could end up doing the dual degree with the worse of both possible worlds, mediocre academics and stunted musical growth. I don’t know what program you are at (nor do I want you to say, keep that private), but music schools are not the lax places some think, and while they rarely throw people out of the program at jury time, you could find yourself where your teacher can stop really giving effort to you, and then find you are relegated to secondary orchestras, not great chamber groups, etc. Likewise, if you keep the dual major, you could end up with mediocre grades which would limit what you could do with that, too.
There are possibly things you can do to make this situation work, after all you are a freshman, still only a couple of months into school and still adjusting. The biggest issue I suspect here is time management, you are overwhelmed with the work for the academic classes (bio is time intensive, I never considered it particularly “difficult” conceptually, but like dear old Organic Chem that was my downfall, it requires a lot of studying to remember terminology/nomenclature, the various structures (in a cell especially), the processes of life, it is a lot. I would agree with someone else, I would drop biology until you get a handle on things, if you feel you are doing badly, then drop it now, so it won’t be on your record.
If you are set on staying with the dual degree then you have work to do. There are no shortcut when you are doing a performance degree, you can’t get by with an hour a day of practice (let alone practicing orchestra/chamber parts), and likewise if you think you want to go into a health field (medicine, veterinary, opthamology, etc) you will need to have strong grades out of your other degree. Bad grades on either side could hurt your possible future. Schools , unless they have changed, usually offer things like time management courses, study skills and the like, to allow you to better user your time and I highly recommend using anything like that. College is very different than high school, no nagging parents setting the structure, and there likely isn’t anyone keeping that close an eye on what you are doing (other than yourself), so it can be hard to use all the time you have, it is so nice after 12 years of class after class, structured schedules for EC’s after class, and the like, to actually have free time, but that also can be a hole (and yep, it is a rabbit hole I had to deal with personally:). I would recommend if you can cutting down the academic work load, since you also have fun things like music theory and ear training to contend with, try not to overextend yourself.
Are you trying to do this in 4 years? Most dual degree kids I have known take 5 years, and you may be trying to do too much trying to get this done in 4, project out what it would look like with 5 years and see if you can make the load any lighter. If you have to finish in 4 years, then one option might be doing summer classes to get rid of requirement classes and the like, so you aren’t killing yourself during the school year.
2)Alternate option 1: Drop the BM degree, and do an academic degree only. Depending on your school, you could still do music, take lessons and so forth (and it depends on the program you are at), simply not majoring in it. The downside is you likely would drop the music theory and ear training classes required for the BM, and may not progress as fast as you would in a BM program. Also, in more than a few programs non majors may not have access to the teachers in the BM program (often they get grad students) and may have access only to non major orchestras and chamber groups, where the level may not be so great, other places you may still be able to play with majors, all depends. This way you can still have music, but focus on the academics as you may want.
3)Alternate option 2:
As compmom wrote about, you could still pursue a health related field after getting a BM, so you could drop the dual degree and stick with the BM. If you think you still want to be pre health (which is not a major BTW, it is an area of concentration), you would have to take the required courses, usually a year of bio at least, 2 years chem (maybe 3 years now, used to be inorganic and organic), probably a year of physics, some math classes, to get into a health related field post grad. The good news is you can take those classes after you graduate (many schools now have programs for people with bachelors to ‘fill in’ the missing courses for pre health) or do them in the summer, you have flexibility. One of the problems likely may be mom and dad, who may not see a BM degree as ‘useful’, but if you point out you still could go to med school with a BM, it might make them feel better. You could also point out that outside of certain majors (comp sci, engineering, accountancy, nursing), most college degrees, including business admin and the like, aren’t all that much different when it comes to getting jobs, they don’t really give you direct job skills the way majoring in engineering would, so a BM likely would mean as much (these days, business admin is a dime a dozen major, a BM might actually stand in higher regard in some quarters). It may be a tough sell, but if you really want to take a shot at doing music seriously, going the BM route this way may be a better choice. As comp mom said, you may find that you don’t want to go into a health field later on anyway, so killing yourself with a dual degree may not be great. And in a year or so, you decide you don’t want to do a BM, I assume you could switch to an academic field, last I checked you don’t have to declare a major until your sophomore year.
