If you are not ready to take this test, you can study here.
Match each statement with the correct term.

1. Given: x+ y + z > 0 Is x + y + 1 < 0?
To be y.
Breathe - Create an internal clock around 3 minutes - Benchmark Problems

x + y + 1 < 0 - 0 < x + y + z - x + y + 1 < x + y + z --> z > 1 -

2. Sentence Correction Steps

(1) Stop Signs: 3rd person pronouns (2) Splits (3) Look for parallelism (4) Everything else

When the question has to do with whether a variable is positive or negative - then list negative - positive and zero.

4. Studying for Critical Reasoning
Do so
Joe or his friends are going. --> the verb correlates to the subject it is closed to when 'or' is used.
3rd Person Pronouns -- It - Its - They - Them - Their
(1) ID each question type (To - From - About) (2) What am I looking for? (3) For the question type - what does the answer need to be ...right;...wrong. (4) Work the passage (5) For the passage - what does an answer need to be right (6) For the passag

5. Critical Reasoning: Explain Problems

6. Given jkmn = 1 jk/mn = 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?
Avoid extremes
20 problems --> 35 minutes - skip critical reasoning questions early on (strengthen/weaken) - Skip combinations and permutations; or - absolute values with inequalities

7. If there is a list...
Not Sufficient. jk = mn --> jk and mn = same numbers > 1 or they could equal 1

Root (81) = + or - 9 - 5/root(x) is not simplest form -->5root(x)/x is simplest - (5/(3+root(x)) --> (5/(3+root(x)) x (3-root(x))/(3-root(x))
108 --> 2 -2 -3 -3 -3 12 --> 2 -2 -3 9 --> 3 -3 - Because you cannot be certain that the 12 and 9 share the 3.
