Totally agree with above post. Here's a little cautionary tale for you, from a girl who was pushed into a science major:
I scored above the 99th percentile on my SAT, ACT, as well as the ASVAB (one of the qualifying tests to join the military.) In fact, I just about maxed out the scores on the ASVAB - my recruiter wanted to photocopy and frame my scores in the recruiting office. I usually scored higher on the verbal sections than math sections on all of the above tests, but I was still in the top few percentiles. Given all that, I thought I was hot shit.
In high school, I had only had slightly-better-than-average grades because I didn't enjoy doing homework, but I generally did very well on my exams. I took a lot of AP and honors courses in both math/science subjects as well as the liberal arts, and breezed through them. Then when it came to college, I got a full scholarship to a state school. I matriculated as a biochemistry major because 1.) I've always done really well in those related subjects and 2.) my father is a biochemist, and he pushed me to follow in his footsteps. It was not my top-choice college, but I went there because it had good reputation and the scholarship was quite persuasive as well.
Long story short, I flunked out of college. Miserably. It only took me a semester before I was put on probation, a year to before I lost my scholarship, and then another year before they put me on academic suspension for not making the minimum grades. I hated my major, I hated my courses, and I hated everyone at my school. I didn't even bother attending my classes most of the time. I could rarely be bothered to even leave my room.
Anyway, I was too afraid to tell my parents that I flunked out of college... so I didn't. Instead, I told them I was doing fine, and became a stripper to pay for an apartment away from home and to attend community college while I figured myself out. Before I became a stripper, I also considered the possibility of running away to another country and suicide - being an academic failure is THAT big of a deal in my family, and I was THAT upset about it. I actually managed to pull this off for a while, until I couldn't take pressure of living a double life anymore.
I eventually 'fessed up to my parents. I pulled up my grades enough to transfer to another school. Unfortunately, I'm still a biology major for practical reasons - despite me failing so miserably at my last institution, I managed to pass enough courses in my major that my fastest route to graduation is to continue in my major. I am under a lot of parental pressure to graduate as soon as possible - for them, it's a great source of shame and embarrassment amongst our family and friends to have a daughter who didn't graduate college in 4 years.
Honestly, if I could do it all over again, I wouldn't have even gone to college at all until I was sure of what I wanted to do. I didn't discover my love and talent for physics until just last semester, when I aced my physics course. (Until then, I had always done rather poorly in physics - another reason why I chose biology/chemistry.) If time and money weren't issues, I'd probably pursue a degree in either engineering or physics instead of biochemistry. It's amazing what motivation can do - despite my past track record of laziness, I'm actually doing quite well now. My current school is a lot more academically rigorous than my last one - if I had put in a quarter of the effort that I am putting in now, I probably would've graduated a year early and with honors, no joke.
I'm not going to lie - being a stripper was probably one of the best and most formative experiences of my until-then overly sheltered life. I learned a lot about myself, about other people, and about the way the world works. It was a better education than I could've gotten at school. It also changed me to WANT to become a better person and to WANT to use my (other) talents to do useful, constructive things. Without all that, even if I had managed to pull up my grades to go back to school to please my parents, I probably would've fallen back into a cycle of avoiding class and failure all over again.
Moral of the story is, let her do what she likes - for herself, and not to please you or anyone else.
