Hello there! Welcome to Gooy’s Mathage Shop!
Mathage = Math + Massage.
This video is the 17th episode of GMAT Challenge 2018. In this challenge, I attempt to solve all problems (problem solving & data sufficiency) from GMAT Official Guide 2018. I try to use the most efficient method. Hopefully some of these videos could help someone.
Enjoy!
