## Data Sufficiency Questions

**Data-Sufficiency questions follow the American style of multiple choice tests, with 5 answer-choices, only one of which is correct. However, the answer choices are do differ significantly from the standard multiple choice format, in that they are always the same. Kaplan introduced a good mnemonic for memorizing the answer choices: 12TEN. Manhattan Prep, a Kaplan subsidiary, advocates a workflow for solving DS questions. It can be a bit unwieldy, so take the time to consider other options.**

*WHAT IS TESTED ON DS?*

**DS questions, as these are known, are based on topics from the standard American curriculum of Arithmetic, Algebra, Geometry, and Statistics, at an elementary level. However, these questions are more aggressively logical than are PS questions - which follow the familiar style of multiple choice question. You can and should read more about these issues here.**

*DS TIME CONSTRAINTS*

**For any quant question, the average time constraint is 2 minutes per question. However, this is only an average, and in reality you may succeed in spending far less time on a DS question. Even if not, just make sure to finish the whole section within the total time budget of 32 minutes. A good workflow is imperative for these questions, even more than for PS.**

*SKIPPING QUESTIONS*

**Since the adaptive test algorithm is adjusting itself to your performance, it will not allow you to literally skip questions, or to go back and revise your answers to previous questions. You may ask yourself, What should I do when I can't answer one of the questions? As a final resort, choose a random answer, just to move the algorithm forward and avoid tanking the entire test. In fact, you can assume that the test already has a good estimate of your final score, so that any one particular question is not that important. Skipping it - by choosing a random answer - won't make a big difference to your score, provided you return to your baseline performance on the next questions.**
