Well I am completely stumped. I scored a 500 on my Knewton diagnostic about 6 weeks ago. This was after 6 years out of college and not looking at any algebra since 2004. Expectedly, I got a Q28. That being said, I took two more practice Cats from Knewton and received a 490 and 540. The 490 was after receiving the 540 about 3 weeks after I started the Knewton online course! Anyway, I took my first Manhattan Cat about 2 weeks ago and found the Quant section to be MUCH easier than the quant I saw on any of the Knewton Cats. On my first Manhattan Cat I scored a Q35. This was about a month after studying with Knewton.
In any event, I took my first GMAT prep diagnostic about a week ago and received a very discouraging Q21! I was really shocked by this as I had been studying for over a month and many of the algebraic concepts I had lost had come back to me. Moreover I though the Quant section on GMAT Prep was actually EASIER than the Manhattan or Knewton CATS. How I scored so low I do not know. The only thing I can attribute it to is that I had to take a painkiller before taking the practice CAT due to a splitting headache. In any event, I was completely performed by my performance. Then, a few days later I took another Manhatta Cat and scored a Q29 V38 (560 overall)
. Most of my errors were careless mistakes on the quant. It seems I'm really having trouble with the timing. I also had to take this while on a painkiller. Just my luck I'm having problems with migraines and headaches less than 3 weeks before the real thing.Anyway.....my question is how accurate are the Manhattan CATS? I feel really comfortable with the math concepts there. Taking a Knewton CAT has been so discouraging. So much in fact that I don't look forward to taking the three I must take in order to qualify for a refund. I'm thinking Knewton purposely makes their practice CATS harder. Anyway thoughts on my wild performances?! Thanks.
