What are people's take on the following
The questions in the OG are real GMAT questions. However, are they all the easy questions (i.e. Bin 1 type questions - using the terminology from the PR)? all the difficult questions (Bin 4 types)? or an equal distribution of questions from all difficulty bins?
The question arises because I appear to be burning through the CR questions in the OG with ease (and on time). I want to be sure that I am studying from a resource that provides questions at a level above
where I need to be to kick some GMAT butt.
