Hi there,

I know this has been discussed before...but I am really freaking out.

I have my GMAT in 2 days and am getting huge variations in my CAT scores 640, 590, 690, 590). And strangely I am getting scores 50 points lower than when I started the Knewton course - although I have found it super helpful. Before the course I did a 2 weeks using manhattan books and their exams in which I was getting 640-650 consistently but then I felt so much less well prepared.

I am really freaking out as I need to get a good score (my aim 680-700) and can't retake!!

Any advice or explanations?!

Thank you

Learning more stuff -- new strategies, new rules -- can lead to (temporarily!) lower scores. When you know more ways to handle a problem with exponents or learn more grammar rules (for example), your mind has a longer list to go through on a given problem. You may choose the wrong rule from the list (since there are more things you know).

+/- 30 points is super-common. +/-50 is less common but this forum is filled with people who have had that.
