How good is 730 on Kaplan CAT1 Diagnostic?

Hi All

I have been GMAT Club member for quite some time. I have been preparing for GMAT exam since last 7 weeks and have my exam scheduled in another 3 weeks.

I scored 730 (Q-98 percentile, V-79 percentile) on Kaplan CAT 1 diagnostic. Is it anyway comparable to actual GMAT exam?

Also, I faired poor on RC. Any good visual techniques for fast reading and increasing accuracy.

Thanks
Saurabh
