Ever struggle to figure out how to convert an official exam score into a percentage that a student might better understand? Struggle no more because I've done the work for you! All you have to do is select the tab for the year of the exam you administered (1994&1999 are available on the free version; up through 2016 on the paid version) and enter the points earned on the multiple choice section and the points earned for each of the two FRQs. The spreadsheet will do the rest for you. You will get a composite score (out of 150), an AP score (1, 2, 3, 4 or 5) and the student score converted into a percentage (0-59 for a 1, 60-69 for a 2, etc.). There are even spaces for 116 student names. If you need more, just copy and paste in a few more rows. The first several rows have been filled in by me to test the calculators at the boundaries between 1s(Fs), 2s(Ds), 3s(Cs), 4s(Bs) and 5s(As) to make sure they work. One thing you'll notice is that I've made them forgiving at these boundaries so a 79.45% rounds up to an 80% rather than rounding down to a 79 which is mathematically appropriate (for the purists). It's very unlikely that you'll have a student benefit because it's so close to 0.5 but it will allow you (as it does me) to point to your efforts to give the "benefit of the doubt" when defending a grade to the student, a parent or an administrator. If you want the 0.5 cutoff, just send me a message and I'll fix it for you!
