How Many More Hours of Tutoring Would You Recommend I Get?

I am just finishing off 12 hours of tutoring with Revolution Prep and my parents and I have agreed that I need probably some more hours perhaps in a couple months. Should I get another 12 hours? 24? Or even 36? My baseline score for the SAT is currently a 1190 and I intend to begin studying between now and the couple of months between when I will start more tutoring but I’m not sure what to do next. Thanks!
