I'm sure you were expecting this so I'll be blunt, I think you have zero chance with those scores. Do something different this time around when you study. I used Kaplan only and it worked wonders for me. If I'd been aware of the other resources, I would have used them too. Spend the money to get the help you need!
BTW- fortunately your RC is good, b/c that's the only one that can't be fixed with a few months of studying. With a 3.5 GPA and 19 RC, your other scores should be much higher.
