Subject : gmat

Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. Critical Reasoning: Explain Problems

2. Given: x+ y + z > 0 Is x + y + 1 < 0?
To (Bring new info; Avoid weak wording) - Strengthen - Weaken - Evaluate
x + y + 1 < 0 - 0 < x + y + z - x + y + 1 < x + y + z --> z > 1 -
Not Sufficient. jk = mn --> jk and mn = same numbers > 1 or they could equal 1
What are they really asking? What are they really telling me? Focus on the minimum?

3. When choosing numbers... don't choose 0 -1 or any number in the numerator or denominator

Many geometry problems come complete with a diagram drawn to scale. Most people get so caught up in solving a geometry problem geometrically that they forget to look at the diagram to see whether the answer is reasonable. Simply using approximations
