I’m only a student but I can share what I know. It’s quite funny…I am a junior majoring in international relations as well, but seriously contemplating a switch back to Physics (which would include my passion for Astronomy and space)
To address your “capability” concerns…I don’t think there is such a thing as being “good enough” or “not good enough” to learn the heavy math and science. A total bum who has never studied in his life could turn around and start pursing a math major tomorrow, if he dedicates himself to the rigor and work that it will require. So worrying about specific grades in the past I don’t think should have much influence on what you choose to do. I got Bs in high school, including in AP Physics. I got a 3 on the AP Physics exam. I got a C in college chemistry. But I look back and realize I wasn’t putting my full effort into it. I know in my heart that I can learn the high level math if I dedicate myself. For me, it’s just deciding whether or not that is what I want to spend my time doing. There’s also that saying…the straight A students work for the B students…
I would also look at Astrobiology if your school has that major. That would be the perfect way to go I would think. I would also not totally disregard your international relations interest. I’m trying to find a way to hold onto mine, too. Perhaps considering minoring in Policy/Government or some type of major like that.
BA usually means a few less “technical” or “math-heavy” courses than a BS. I’m not sure why the Biology major would offered as a BA.
It’s refreshing to see other people who seem to have visions similar to mine: How can we find a way to combine international politics and science in order to advance knowledge across the world and meet new scientific goals for our society?
I think we’re going to be great at it…
