Got my first chemistry exam back this week, and -- though I didn't want to publicize this -- I made a 75. That's not good enough for me, but also I should say that it is actually a B in this class, and it is exactly the class average for this first exam.
But can I also say that I got several questions wrong because I hadn't memorized conversation tables? Such as, how many micrometers are in a meter? I took a guess at that, and got it wrong. If I had had my note card with the conversion tables, I would have been able to do the problem without error. I just don't think it's that important that I have those things memorized, but that I can do the conversions and figure out units for the problems. I also had to memorize the solubility and insolubility rules for a quiz. I can only imagine that chemists have those things memorized, but because they use them so frequently. But first-year chemistry students? Just knowing that we need to refer to the solubility rules and how to apply them should be enough.
