5-10 hours of test prep may add a couple hundred points to someone’s score, but probably won’t take someone from ann 850 to 1200. Looking at the math section, you might get a 600 if you don’t study but could know all the material but don’t know how to take the test. But to get a 600 requires you to know a certain amount of material and know how to take the test. Most kids at my HS couldn’t get a 600 math even with 40 hours of math prep.
