The CD questions are NOT adaptive. We offer a variety of difficulty levels on our materials, but the only adaptive pratice we have are our CATs.
There are definitely 700 level questions in GMAT Premier, but not to many of them as Swoosh pointed out. You can find more, tougher problems in Kaplan GMAT 800
, or by doing well on our adaptive mock exams!
Hope this helps, and thanks for choosing Kaplan
I will do the CATs later on, working on the CR part now, and it is good to hear some question are 700 level, and I did good ( 5 mistakes out of 66 questions)...it builds self-confidence!
