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. Given jkmn = 1 jk/mn = 1
Two independent sentences
Not Sufficient. jk = mn --> jk and mn = same numbers > 1 or they could equal 1
(1) What is the antecedent? Is it sensible? Is it present? Is it unambiguous? (2) Do they agree in number?
Seven-store retailer is singular - therefore its is the correct pronoun. one action is the seven-store retailer saying something and the sales slump -- the sales slump preceded reporting about the slump; therefore - it needs to be in the past partici

2. nouns
Go slower.
5 problems --> 65 minutes remaining - 10 problems --> 55 minutes remaining - 20 problems --> 35 minutes remaining - 30 problems --> 15 minutes remaining - 34 problems --> 7 minutes remaining - Skip between questions 3 and 8.
Look for verbs
Analogy

3. For studying sentence correction
the GMAT will always put the comma on the last
Go straight for fractions
(1) Recognition (2) Content (3) Circle right answers and explain why the others are wrong (4) Train your eye to notice stop signs (pronouns)
z > x + y + 1 - x + y + z > 0 - x + y + 2z > x + y + 1 --> z > 1/2

4. Given jkmn = 1 j = 1/k; m = 1/n
(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
Cannot introduce examples -- such as must be used instead
To
Sufficient.

5. 42/x = Integer/1
z > x + y + 1 - x + y + z > 0 - x + y + 2z > x + y + 1 --> z > 1/2
The second sentence focuses on the extent to which the children are covered in mud.
Write your integers like this
Sufficient.

6. How to do assumption problems?
(1) Read question first (2) Read for structure and look for gaps (3) Work from wrong to right (4) Negation test: If you negate the argument will fall apart - Answer choices that bring in new information are wrong - Look for reverse causation
Be estimated
Look for verbs
y is 2 more than a multiple of 3

7. Verbal Problems Timing strategy
Draw a diagram. The first thing you should do with any geometry problem that does not have a diagram is to sketch it out scratch booklet. And when you draw the diagram - try to brought scale that way be in a position to estimate.

the GMAT will always put the comma on the last
20 problems --> 35 minutes - skip critical reasoning questions early on (strengthen/weaken) - Skip combinations and permutations; or - absolute values with inequalities

8. Do not divide by variables in the inequalities if... you don't know the sign

20. How to eliminate answers on geometry questions
Mal's room is so clean that his mother praises it. A possessive noun must match only with a possessive pronoun.

We are in the 'To category.' So - we bring something to the argument. It will not break the premises. For example - Mary: That guy is a newspaper reporter...; Joe: No! That guy wears a cape! Therefore - it is superman. We focus on explaining!
