I was wondering if college board would delete or cancel his scores in anyway due to his huge improvement?

Hello Mike!
In 2015 January, my friend got an SAT score of 1750. From then on, he has been seeing huge improvements on his practice tests through painstaking practice (he’s now getting 2250-2300). I was wondering if college board would delete or cancel his scores in anyway due to his huge improvement? He’s going to take his second SAT on November and his worried that he’d be accused of cheating or have his score canceled.

Thank you so much for reading!

Hello Mike! I’m kinda stuck on #17, pg 273 on the Patterns section…

Hello Mike!
I’m kinda stuck on #17, pg 273 on the Patterns section. The question is the first term in the sequence above is 3, and every term after the first is -3 times the preceding term. How many terms in the sequence are less than 1000? The answer is more than 9. But then if you do multiply the preceding numbers by -3 you get -81, 243,-729 (these 3+before 3)=6. You get 2187 if you multiply -3 by -729 so it doesn’t count right?
