I wish you success, not luck! Back in Catherine and my days, the exam was four parts over two days (8 to 4:30). The third part was corps, which has now been rolled into the business/entities part. That change puts all the worst cougars in one cage. Everyone thought individuals would be a breeze, but that was not at all the case. I too passed all four parts on the first try, but my corp score was barely passing. Back in those days, you got to take your exam home with you because everyone got the same one at the same time. You could contest answers graded wrong, and the professional associations dug in and did just that. After the corrections (two answers correct, all answers correct), my corp score went into the high 80%s. Can anyone contest answers anymore? A disadvantage we had is that passing scores were curved, like the CPA exam, so if a bunch of geniuses happened to take the test when you did you might not pass with the same score you earned at a different sitting.
Do your best, answer every question even if it's a wild guess, and do NOT go back and change any answers. Time again, that practice has proven to be fatal.
