I have my raw scores, what do you think my projected SAT scores will be? please help?

I have "The Official SAT Study Guide" from CollegeBoard. I took a practice test from that book. I timed myself, and made sure I never went over the time limit. However, I span the test over a few hours. For example, I did 3 sections, then took an hour long break, then 2 sections, then 3 sections. So, the raw scores are:

CR: 54.25
Math: 48.25
Writing: 39.5 on MC, and 8 on essay.

Yes, there is a conversion table from raw to scaled scores, however it differs a lot. For example, 50 on critical reading would be 600-660. But I was wondering if anyone could scale my raw scores based on prior knowledge or experience and perhaps give me an accurate measure.
Thank you.

I bet if you did it yourself, you could increase your raw math score to 52-54. Thats great that you are practicing ahead of time though!

This is a rough conversion:
CR: 670
Math: 700
Writing: 620 (64 subscore on just the MC)

Think of these scores as the middle of a range of scores. Depending on the difficulty of the individual sections on your test, these scores could be 30 points too high, or too low. Your math score is fantastic.
