They're different than bio. I would say that if you can do well in chem/physics, you can probably figure out how to do well in bio but not necessarily the reverse. In order to do well in chemistry and physics, you have to really understand the fundamental concepts, principles, and where the equations come from. Memorizing the equations isn't going to be enough to get you a stellar grade. You have to be able to recall the correct concept/principle to apply in a new situation and then successfully apply that principle, which requires critical analysis. That doesn't always happen in biology, where it's more memorization heavy, i.e. if you don't know that the mitochondria is the powerhouse of the cell, it's really hard to reason your way there.
