Amazing Tests

I gave my GMAT exam in January totally unprepared. just going through few 100 questions in the GmatClub CAT's and I was amazed that i could see similar pattern questions that wouldn't have taken me more than a minute to solve if i would have prepared better.
These CAT's are worth the money to spend on them for the quality and quantity of questions they have.
I again bought the CAT's and preparing through them. Moreover the forum is of great help. The kind of material that is provided is incredibly commendable. I am currently following bunnuel's posts for quant and souvik's posts for verbal. hope i can achieve my target score this time.
