if you're serious about the 170, take the full course! it's an investment, and it'll be time and money very well spent. you don't really need a 170 for Franklin and Pierce, anyway. I also don't want to burst any bubbles you may have, but a 170 is a long shot. I mean that is a 15 pt increase! 10 is TM and powerscore average, and when the numbers get the 1650-170 range, they're really hard to improve. I'd say to honestly expect a 170, you should expect starting with above a 160.
