I'm really wavering over the idea of signing up for organic I and II courses that are close to starting but I'm a bit leery of doing so. I had taken general chemistry back in 2007 and although I passed with a B, I struggled mightily. I'm reading other posts that despite its daunting appearance, taking two chem courses over the summer is doable. But do you think it's doable for someone like me who needs a refresher course?
