The EA scoring system differs from the GMAT’s one as it is section-adaptive and your performance in the first section (Integrating Reasoning) will heavily impact your final score.
Each section of the exam is given to you in two panels. For example, the Integrated Reasoning (IR) section has two panels of six problems each. Your first set of six problems will be of mixed difficulty (mostly at a medium level). Within that panel, you can jump around and answer the questions in any order you want. After you submit your first panel, you’ll get a second panel; the difficulty level will depend upon your performance on the first panel. If you get everything right, your second panel will be quite a bit harder. If you miss every question, your second panel will be quite a bit easier. Most likely, you’ll be somewhere in between those two extremes.
After you do the two IR panels, you’ll start the Verbal section. The level of difficulty in your first Verbal panel (seven problems) will be determined by your performance in the IR section, and your second panel of seven Verbal problems will be determined by your performance on the first Verbal panel. Quant will work the same way as Verbal (your starting point is determined by IR, and your second panel is determined by your performance on the first Quant panel).
The Executive Assessment is a relatively new test and there is not enough data yet to pinpoint what a good EA score is. However, for top business schools, we advise our students to score 155 (~80th percentile) or above. A score of 150 is ~53rd percentile and 162 is 96th percentile (GMAT 730 equivalent) It is important to note that of all 3 sections, the Quant score will be the most important and we advise to reach a scaled score of 12 or above.
