I worked through the OG (12th Ed.) the last few days, and my scores for each section are as follows:
Problem Solving: 218/230, 95%
Sentence Correction: 132/140, 94%
Reading Comp: 131/139, 94%
Critical Reasoning: 110/124, 89%
Data Sufficiency: 148/174, 85%
Question 1: Are all the sections in the OG weighted equally on the test? Or are certain sections of the OG (like DS) composed of questions that are deliberately harder?
Question 2: How well do scores on these sections of the OG compare with peoples real GMAT scores?
Thanks for your help!
