Charles from GMAT Ninja explains how having a systematic
approach to solving questions can help eliminate careless errors and
manage time better, ultimately leading to improved quantitative
scores. The focus of the video is on process rather than complex
math problems.
Charles emphasizes that the video is important for those struggling
with quant, regardless of experience level. The goal is to teach
processes that will help test-takers stamp out careless errors and
manage time more effectively.
The video begins with a standard problem-solving question to
illustrate a good problem-solving process. The questions used in the
video are mid-level questions, and the objective of the test is to find
the level of question at which a test-taker gets half the questions
correct and half incorrect. Thus, getting an easy question correct
leads to harder subsequent questions, but incorrect responses to
easier questions can lead to lower scores.
The video concludes with an explanation of the three-parameter
logistic model and a four-step process to execute it. Charles stresses
the importance of consistency in problem-solving to improve
performance, even if it is not the most exciting aspect of exam
preparation.
Hit pause as needed, but make sure to watch the entire video to
learn about crucial techniques that can make a real difference in
your performance on GMAT and EA Quant exams.
The way GMAT questions are often written, one can misread one
little modifier and end up in real trouble. Therefore, it is advisable to
read the question twice every single time and plot your path forward
before jumping into typical questions. Take your time to read and
try to find the best way forward before jumping into typical
questions so that you don't waste a ton of time, run behind
schedule, and scramble because you've picked suboptimal paths.
It's hard to pick the perfect path on all the questions, but you can
always read a couple of questions and honestly assess if the path
forward is feasible or garbled. If it's garbled, walk away and move
on, and remember to check your work as you go.
Sometimes, we all make mistakes, and that's understandable.
However, the key is every time you write something down, be it a
line of algebra, arithmetic, or geometry figure, check it by asking
yourself if it is correct and if it's in the right ballpark. Checking your
work every single time is crucial, as it helps you to see the little
