Sparkly,
I am the true Some Common Sense. As a Professional Chemical Engineer, I had to take a LOT of chemistry, physics and math. OChem does not have to be hard except most people find it so because 1) there is a lot of material to memorize and 2) you must apply it. Most students learn to memorize and regurgitate what they memorize; this one of the first major classes they must apply what they learn. So, use this class to adapt to learn this skill; you will need to for your future.
