Math; we covered adding and multiplying Matrices and building a matric out of a set of equations. Apart from the "Oh, neat!" factor, I'm not entirely sure where I would apply these; systems of solutions are much easier for me to handle. I do see where the concepts of Matrix math work into building arrays in programming, so there is that.. I got a 97% on the test. Mostly what I missed were silly things. In one problem, I used a "3" instead of a "-3". In another problem, I circled my final matrix as the solution to the problem instead of the ordered triplet. Both of those are silly mistakes but I guess, yes, they were mistakes. Another point was lost when I wrote "Orders do not match." for the answer to a problem that involved adding two matrices together. The teacher counted my answer as "wrong" and said I should have said "Not possible". Uhm... Pretty sure I implied thta by not trying to answer the question, but hey. To move a score from 97% to 98%... not worth quibbling.
Chemistry was stupidly simple. We covered shapes of molecules, hybridization of orbitals, and the ideal gas law. Herp. 103% on that test.
