I was a math/biology double major until a calculus class that reqired using the method being taught I tried, but sometimes I'd forget the formula, and derive it- or another applicable one - so even though the answer was right, the work I showed was "all wrong".
Wow, are you sure you aren't me? Calculus is what changed my Math/Biology major too my freshman year in college... not because I didn't understand it, or didn't get the answers correct, but because I was unable to show the "correct" work. For me, it was work on the computer, in a specific program. I could use paper and formulas all day long, but I could not translate it to the programs being used on the computer. And not to show my age too much, but I took a real typing class on a type writer when I was in high school, so computers weren't quite what they are today (or at least we weren't using them as we do today).
