Question on 'Practice'

[Bullzi]

Hello,

I am on Day 5 and there is a mention of practicing questions from the Official Guide for GMAT Review. Now, I was a little confused if the practice question numbers referred to in the email are from the Diagnostic Test section (section 3) or the Problem Solving section (section 5) in the OG. Please help!

From what I could see in the questions, it looks like the reference is to the Problem Solving section, but, I just wanted to be sure..

Thanks,
Bullzi
