Thanks for the many replies!
So to answer all of you:
I did indeed take a Manhattan CAT before I started to study with quant and verbal in the 30s (can't remember the exact score)
So I started the TTP study plan and learned alot (really alot)
Then i took the official pratice Exam 1 which I felt was too dificult for me so I stopped ..
And I have never seen the questions of Exam 2 before and have done it in the time given so from that point of view it should be "reliable".
But the thing is there were only a few probability Questions and I think no Combinatorics questions and I thought most hard questions are from those topics.
But well if you guys tell me that this should be similar to what I will see on test day, I am happy!
I thought I take the gmat this week but then decided to give myself more time and I want to do it in end of August!
