**TEST IT**

**The most powerful EMPOWER tactic for the Quantitative section of the GMAT**

**WHY use TEST IT:**

1. On many questions, it’s an easier/faster approach than conventional math

2. It’s useful on up to 2/3 of Test Day Quant Questions

3. It’s useful on most Data Sufﬁciency Questions

4. You cannot earn a 700+ without TEST IT

**CLUES that you can likely use TEST IT on a question:**

1. When there are one or more variables in the answers

2. When there are one or more variables in the prompt

3. When math vocabulary words (odd, even, positive, prime, etc) appear in a question

4. You’re on a Data Sufﬁciency question

5. If you’re not sure how to begin a question

**HOW to use TEST IT:**

1. Look for VARIABLES (in the prompt and/or the answers)

2. Identify any math rules or deﬁnitions about the variables

3. Select easy-to-use numbers for your variables

4. Perform any necessary calculations that the question asks you to perform

5. Compare your result with the answers and ﬁnd a match (when variables occur in the answers, then you must check ALL 5 answers)

**Example:** If N > 4 and N is a prime number, then what is the remainder when N² is divided by 6?

(A) 0 ** (B) 1 **

(C) 2

(D) 3

(E) 4

**WHAT number(s) to pick:**

1. In Problem Solving questions, small integers tend to be best (2, 3, 4, 5, 6, etc.); avoid the numbers 0 and 1 except in complex questions

2. In Data Sufﬁciency questions, ANY numbers are permissible, as long as the question doesn’t restrict it (look to use 0 and 1 in these situations)

3. Use 100 when a % symbol appears (or percents are referenced)

4. Use the common denominator when a question lists fractions in the prompt

5. Use numbers that match any descriptions given (odd, negative, prime, etc.)
