The Oracle Application Grid 11g Essentials exam includes 70 - 75 questions to be completed within 120 minutes. Do the pacing math before exam day: with that many items on the clock, you need a steady rhythm and the discipline to flag a hard question and move on instead of stalling. Two or three full timed sessions with the ActualCollection test engine will show you exactly what that pace feels like, so time pressure stops being a factor on the real day.
To pass the Oracle Application Grid 11g Essentials exam you need 63% - 64%, and the official registration fee is USD 245. A retake is not discounted: a failed attempt means paying the full USD 245 again, so treat your first sitting as the expensive one.
