GMAT Crash Course: All In One - 2

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. Sentence Correction Steps
(1) Stop Signs: 3rd person pronouns (2) Splits (3) Look for parallelism (4) Everything else
20 problems --> 35 minutes - skip critical reasoning questions early on (strengthen/weaken) - Skip combinations and permutations; or - absolute values with inequalities
Go slower.
(1) Find conclusion (2) Relate each bold point to conclusion - Supports the conclusion - It is the conclusion - Supports the other conclusion - It is the other conclusion (3) Tell each answer choice what it should say

2. Compare with
(1) What is the antecedent? Is it sensible? Is it present? Is it unambiguous? (2) Do they agree in number?
Cannot be measured
Memorize the following approximations: Pie approximately equals 3 - Square root of one equals one - Square root of two approximately equals 1.4 - Square root of three approximately equals 1.7

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))
