Based on my analysis, the

OG 13th edition difficulty breaks down like this:

Problems Composite Score Level

First Third 500

Middle Third 550

Final Third 650

These divisions apply to each problem type in the OG. A 650 composite score means that a student is getting half of the problems at that level correct. So, if you are acing the final third of the problems for each problem type within official timing limits, then you are actually performing at a level higher than 650.

This analysis comes from my guide to self-study:

GMAT Clarity.

As per now, I solved 0-100 numbered questions(Problem Solving) yesterday, I had 95% accuracy at the problems and solved each question in around 50-90 seconds. So, what do you think?
