You can do it!! I took organic, physics, physics lab, organic lab, p-chem, 4th semester spanish, and latin/greek class together and ended up with all a's, except for organic, in which i got an 86%. However, I hardly got any sleep at all that semester (second semester sophomore year). Just make sure that you have your head on straight and are willing to commit to studying. If you can, though, I would take as few "hard" classes as possible with them. Hope this helps ya!!!! GOOD LUCK!
