Ever heard of a Math problem that you actually don't have to solve. If you have just started your GMAT prep, then this can be confusing. Don't worry! With some practice, your mind will be trained to think like a DS Wizard. Follow these 10 tips and you will be on your way to mastering GMAT Data Sufficiency.
1. Familiarize with the Answer Choices
No excuses: On Data Sufficiency, they’re always the same! Know in the blink of an eye what choice C is. On test day, if you find that Statement 1 is insufficient, be able to cross out choices A and D without hesitation.
2. Takes notes efficiently
Each statement alone will be sufficient if both of the statements on their own contain all the information necessary to answer the question. The statements will be sufficient together if they contain every piece of necessary information between them. Take the area of a parallelogram: Do you need to know every side length to determine the area? If you have every side length, can you find the area?
3. Don’t look at the statements together.
Statement 2 may tell you that x is negative, but that fact has no bearing on Statement 1 when viewed by itself. Explore all the possibilities offered by each statement individually. If you’ve...

Categories : Data Sufficiency Data Sufficiency questions are not the same as your regular "Find the value of x" question. GMAT DS Questions require you to adjust in your approach to Math Problems. You are not primarily concerned with the final answer, but rather whether you have enough information to get you to that answer. For example, if you’re asked to find the value of x, and a statement tells you that 300x + 257 = 1345, you know that this statement is sufficient, because you can perform arithmetic on that equation to isolate x. Are you going to perform it? No, because it’s too complicated and you don’t need to! All you’re concerned with is whether you can find the answer. |
During GMAT Preparation, Critical Reasoning and Data Sufficiency sections require a great deal of adjustment compared to GMAT Reading Comprehension and Sentence correction, as the latter follows a format that you have seen in Computer Adaptive Tests, undergraduate level tests, and other job interview evaluation. The linear thinking that involve variables, data substitution, rules, and logical thinking might not completely work for 700+ GMAT CR and DS sections. |
To score 700+ on the GMAT, test takers must develop a strategy to answer the Quant questions in 2 minutes and Verbal questions in 1 minute & 20 seconds. Data sufficiency questions can be solved well within the 2-minute mark, most likely in 1 minute and 30 seconds if the conditions and question are rephrased. Not all questions will be required to be rephrased but there are certain conditions where this technique is extremely useful, especially when concepts in Ratio & Proportion, Equations, Inequalities & Divisibility are tested. |

Categories : Data Sufficiency, GMAT Process of Elimination Once GMAT test takers have learned about the fundamental concepts tested in the exam, focus should be on saving time for each question. In GMAT, each question should be answered in just under two minutes. Data sufficiency follows a format where a question is followed by two statements, labeled as (1) and (2), and five answer choices in the format: |
