Math 101
There are two types of questions on the GMAT math section.
Problem Solving
Problem solving questions test basic math. The format is a simple multiple choice question with five choices.
Data Sufficiency
If you have never taken the GMAT, data sufficiency question unlike anything you have seen before. There is an important distinction between data sufficiency questions and problem solving questions. Data sufficiency questions don’t ask you to solve the question. They ask you can you solve the question. Here is a typical question:
What is x?
1) x- 2 = 5
2) 3x = 21
Here are the answer choices. Don’t worry after a while they become second nature.
a) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
c) Both statements TOGETHER are sufficient, but NEITHER statement alone is sufficient
d) EACH statement ALONE is sufficient
e) Statements (1) and (2) TOGETHER are NOT sufficient.
Strategy for Data Sufficiency
1)Memorize AD or BCE. These are always your options. Cover up Statement 2.
2)If Statement 1 alone is sufficient write down AD. Then cover up Statement 1 and look at Statement 2. If Statement 2 is sufficient as well, mark D as your answer. Otherwise A is your answer.
3)If Statement 1 alone is not sufficient write down BCE. Then cover up Statement 1 and look at Statement 2 alone. If Statement 2 is sufficient, mark B as your answer. Otherwise, check both Statements together. If both statement are sufficient, mark C an your answer. Otherwise, E is your answer.
