GMAT OG 2018: A quick overview
The OG 2018 question distribution is out, and it seems that the GMAC has released 122 new Quant and Verbal questions (~15% new content). As usual, this means that they have also taken 122 (of the existing) questions out. Although we'll need to wait a bit to see all the new questions, we have the following information:
* Note: for all charts, green dots represent new questions and red dots represent questions that have been dropped. The X-axis represents the order of questions, and the Y-axis is meant to represent level of difficulty (OG questions are ordered by difficulty). The GMAC says that the classification is broad (think easy/medium/hard), so don't assume that the questions on the extreme right are the toughest the GMAT has to offer!
Problem Solving: 35 new questions (out of 230)
Data Sufficiency: 26 new questions (out of 174)
Reading Comprehension: 21 new questions (out of 139)
Critical Reasoning: 19 new questions (out of 124)
Sentence Correction: 21 new questions (out of 140)
From these charts, it does look like the GMAC has front-loaded the new questions, at least in Problem Solving and Data Sufficiency. But don't let that keep you from using these new questions: all OG questions are retired, but actual, GMAT questions! We'll be analyzing the new questions for any patterns and changes. All the best for your preparation!
