Three parts: easy, eh(mostly decimals) and tough but with multiple choices. For the easy part, -3 for mistake or blank. For the medium part, -2 for mistake and -1 for blank. For tough part, -2 (or -1) for mistake, 0 for blank. (obviously +1 for each correct answer)

Did well but made a few careless mistakes and ended up just short of the passing score of 60%.
