Performing well on the quantitative section of GMAT requires a mix of math theory, test taking strategy, and critical thinking skills.

Three of the sandwiches were evenly divided among the students. Since 4 students did not want any of the fourth sandwich, it was evenly divided among the remaining students.

Although there are some rules you need to know, doing well requires that you think in a structured yet flexible way and approach each question as a problem that needs to be solved strategically and creatively.
