Two things:
1) Does anyone know how the OAR is graded? The old grading rubric was on a excel file shows that you can miss 10 questions and get a 63, 17 and get a 53, 27 and get a 43 with a 67 questions exam. Now the test has 87 questions total (20 more than original one) so I am wondering if they use a different grading rubric or something. Don't know if this is like the SAT/GRE where if you answer wrong it counts against you vs. if you just leave it blank.
2) How many times did the computer exam crash for those of you who took forms 3,4,5 on the computer? I took form 3 the first time, studied only a few hours few days before the test, crash free and did okay (OAR 63). I took form 4 recently, the exam crashed 6 times (once in Math when I was half way through, 4 times in Reading section with about 4-5 questions completed where it froze while trying to load the exam, once in Mechanical with about 4-5 questions completed), I studied more, was very confident on Math (I knew I didn't miss a single question on the actual exam and finished with 3mins left) and also more confident on the Reading section after doing practice problems (finished with 2mins to spare) but wasn't too confident on all 30 questions for Mechanical (I knew I missed 2 due to wording), and knew I missed less questions as compared to my form 3 experience, and got a lower score... WTF.
Using the old grading rubric I can believe that I missed 10 questions the first time around with form 3. However, there is no way I missed more than 10 questions when I took form 4 but I did considerably worse. I thought the OAR is a straight forward grading, no bell curve, percentile or SAT/GRE double punishment for wrong type of grading. If they only counted the questions that I answered after each crash then that might explain the new grade but other than that I have no idea where I could of messed up this bad.
Form 4's mechanical section was very strange compared to the form 3 I took. There were a lot of questions on Gases, funny wording on some questions, and very funny pulley setups. It was, imo, more challenging than the practice problems in Peterson. It also doesn't help when the test crashes and the computer eats away precious exam time in a 15min 30 question section. Form 4 also had a strange reading question with a very awkward last sentence that was incomplete.
