@SaphireNY just wanted to add to your argument with a look into my own experience with the SAT. At the end of junior year, I scored an 1840 on the SAT. Seeing as how this would be unacceptable at almost all the schools I wanted, I knew I’d have to study. I studied for about 2 months and took the test in January. What did my studying and practicing garner? 330 points. I went up from an 1840 to a 2170 simply by studying with the SAT official practice guide. I think this was part of the reason as to why I got a likely letter from Duke a few days ago 
It would’ve never happened with an 1840. Best of luck to you all.
On the conversation of the thread: the writer simply has an absurdly inflated ego and seeks to validate himself by bolstering his position from what it really is. Alumni interviewers are amazing people who dedicate their time for their institutions and for the sake of the kids. They don’t however, choose who gets in or who stays out. This guy gives a horrible image of alumni interviewers. They usually rock and are very casual!
