Double and triple majors are kind of silly really. People who do it are usually doing majors so close to each other they have the same prereqs, such as your example of biochem and chem (although government definitely doesn't have any overlap). I know a guy who is triple majoring in chemistry, physics and math, but the physics major requires so much math that you basically have the math by the time you're done, and they're all required to take chem at least through orgo, so they only need one more chem credit (analytical, plus biochem, which they were doing anyway) to get the major He could probably throw in bio without much effort. Really, I think schools should probably stop allowing this. If majors are so easy to pile on, they should probably be thinking about increasing the rigor required to obtain one, and that although you're really impressing your mother, any adcom who's been around the block a few times can see the writing on the wall. I was thinking about double majoring in chem and biology myself. I only need one more chem class next semester (analytical) to do it. But I need at least 12 hours of bio to get the bio degree, and am thinking of taking a senior research lab for credit instead and forgetting about anal. Who wants to do more chem than they have to anyway? I'm sure it will be a semester of hell (upper level chem classes are worse than orgo was, and labs are torture, they hire the TAs solely to scream at you and take off points if you ask questions.) And I'm pretty sure the material isn't going to be useful for medical school. I'll remember the struggle to do it, but forget all the chemistry. Why not concentrate on something that truly interests you and go more in depth into that? Besides, If I really need the wow factor, there's always the BA in music and the BA in german that I got the first time around.
