What should I do next after getting 12 hours of SAT tutoring?

I’m starting to prepare for my SAT and got a tutor and we do two hour sessions once a week for 6 weeks. He’s a great tutor and has taught me some great strategies but I feel I’m still not ready. We would have done 24 hours of tutoring or even 36 but as a result of scheduling conflicts we had to stick only to six weeks (12 hours). Anyway, as I near the end of six weeks I’m wondering would it be best to apply the skills I’ve learned by simply practicing through Khan Academy or prep workbooks, or would you recommend I add another 12 or maybe 24 hours of tutoring?
