14 sections • 66 lectures • 5h 32m total length

A classic student problem7:31
Playing children create a problem5:50
Learn to solve a three-set GMAT problem with a Venn diagram by expressing counts in terms of the all-games variable and computing the at-least-one fraction.
Pieces of pipe lay still for our counting4:42
The lecture models a 1-meter pipe with marks at fractions like 1/5 and 1/15, then computes distances between marks to determine which options fit as piece lengths.
The relationship of a,b, c - Problem?5:20
Solve for the relationship between A, B, and C using exponentials with the same base, and confirm option B as the correct answer.
Rectangle gives us the area of a square4:14

A and B get down to business4:48
Solve a speed-distance work problem where A and B work together, determine B’s fraction of the job, using speed, ratios, and work-time relationships.
The journey of 4 people in 4 seats4:53
Learn how to count seating arrangements for four people in four seats under two driving restrictions: any one may drive, or only X or Y may drive, using factorial methods.
The strange population of a town6:34
Power struggle with A and B4:36
Ways to unite a, b and c5:00

The problem of increasing production5:31
apply the definition of averages to a GMAT production problem to analyze 14-day and 15-day totals. solve for the daily productions x and y to determine the 15th day's output.
Students may come and students may go, the weight goes on forever5:26
A horse and a car compete for speed4:42
A horse and a car race for speed, using 80 mph and an eight-hour head start to illustrate that the same distance yields inverse speed ratios.
Crossing tracks of two trains5:02
calculate the meeting point for two trains from opposite ends of a 1400-mile line at 60 mph and 80 mph, and determine the 200-mile difference in distances traveled.
Mixture in a tank4:31
Solve a GMAT mixture problem where one-third of a tank is a mixture of chemicals and water; water evaporates, and equal proportions yield a 60-gallon capacity.

Fruits in a crate5:38
A small value of X4:33
Choosing between engineers and managers4:52
Analyze a GMAT problem by comparing engineers to managers and determining how many more managers to hire while keeping engineers fixed. The result shows 25 percent as the required increase.
Trading boxes3:45
Two machines compete4:39
Compute the combined production rate by summing the individual speeds of machines x and y, then multiply by 60 hours to determine total units.

Students should be preparing for the GMAT - this course is specifically geared towards that test

The Problem Solving questions on the GMAT are the easiest on the test - which puts the pressure on you, the test-taker, to nail them all.

The adaptive nature of the GMAT makes easy questions hard. Why this paradox? Because when you get an easy question, the pressure is on you to nail it - and nail it fast. If you miss on an easy question, the adaptive GMAT will relegate you pretty quickly to a lower tier score. And trust me, the pressure this puts on you can often lead you to get an easy question wrong. This is the paradox of the easy-but-hard questions on the GMAT.
Problem-solving questions, unlike data sufficiency questions, are very predictable indeed. So - don't fear them. Adopt a methodical, workmanlike approach to these questions, and you will get them right with a minimum of fuss. That's what this class will help you do.
Oh, and quick mathematical shortcuts are a big contributor to success on the GMAT. Use these shortcuts to solve questions in record time, or to confirm an answer you already arrived at using a more conventional technique. This course covers loads of such mathematical mnemonics.
