Is it safe to shop at eBay?

I pretty much figured you would major in music because you assemble your own music pieces which is pretty incredible. Science isn't necessarily hard, but it is tedious. And even though there are some people who can sometimes study at the last minute for some of their classes and still get As, there are rarely any science majors who can study all subjects at the last minute for all their classes and still get As unless they're a genius. Or the science program is just watered down and spoon-fed via lecture notes directly placed on the test which is just absurd.
