I've calculated AP US HISTORY scores for my practice test (1988), and I've discovered that the scoring is VERY lenient. I got 66 questions out of 80 correct, meaning I got 14 incorrect (I didn't omit anything). That, in itself, is a whopping 70 points. Considering that an AP score of 3 is = to 74+, if you manage to score around this much points on the MC, you can theoretically bomb all three essays and still get a 3. 70 points + (1 x 4.5) + (2 x 2.75) = 80
Now, do the math for yourself to confirm this. I just thought this was a neat thing to know, so you people who are prepared with the random MC questions, but are not that good at writing essays. You CAN still pass. All the calculations were made with the official collegeboard grading rubric equation thing. I found a nice link for you guys to experiment with, so you can establish your "worst" case scenario. Cheers, and good luck everyone!
