Retaking the SAT
I have been a university professor, administrator and admissions advisor since 1978....and I have one kid at the USCGA this year.....so this comes from experience. (I am also known to be rather blunt so please don't take any offense at any of my statements here....)
Most people who retake the SAT get at most a 50 point bump the second time they take it, after that there are diminishing returns. Many don't see any change, a third time, some see a slight drop. In general, when I talk to prospective students, I tell them that most of the bump is due to their familiarity with the exam, not with anything they studied. Usually when students take the SAT the first time, they are nervous, apprehensive and don't know what it will be like. The second time they take it they are more relaxed....and I personally feel that is more likely the reason for any bump than extra studying. So I suggest that students who choose to take the SAT a second time go into it relaxed but determined (I know that sounds like an oxymoron, but it really isn't).
What I can tell you is this.....the toughest thing an admissions officer has to do is decide who on the bubble makes it, and who doesn't. If only 100 students can be admitted, ranking numbers 99, 100, and 101 is very hard and is usually based on some intangibles. Even a bump of 10 points on a SAT could make a difference. And if you don't try it, and you don't get admitted, you will never know if you were #101. So I suggest that if you feel he is on the bubble, that he retake the SAT. So regardless of what happens, you will both know you did all you could. Getting a lower score won't hurt, but a higher score could end up being the difference. Don't be surprised if there is little change however, as statistics show very little if any change between the second attempt and any subsequent tries.
Even if he does worse, retaking the exam does say something to the admissions office. I can tell you from experience, (my daughter is just finishing swab summer at the USCGA as we speak), that even the most motivated student will question their decision to attend USCGA sometime during swab summer. (In reality, they will likely question their decision a couple of times per day!)
They have to really WANT to be in the USCGA to get through swab summer and the 4th class year. Part of the reason for swab summer is to determine early on just how badly the swab wants to be there. And about 10% of the students change their mind while they are there and return home.
This is where your son (and not you) have to decide how badly he wants this. Like I said, I tend to be blunt, and apologize in advance if this offends anyone, but if he knows he might be on the bubble, and isn't willing to spend the money to re-test or take the time to do so, then he might not really want in that badly. That is a decision only your son can make, no one else. My daughter hit a few rough spots while trying to get in to the academy, and she overcame them, but the decision HAD to be hers....it couldn't be mine....cause I'm not the one putting up with swab summer, 4 years of a military academy and 5-20 more years in the military. Admissions officers look at this. Even if your son retakes the SAT and does worse, the very fact that he re-took the exam does indicate how badly he wants in...and that just might be part of the admissions equation if he ends up on the bubble. I hope in your case it doesn't come down to that, but in every admitted class, there is the last person to get in, and the first person denied. If you really want in, you don't want to be #101 in a class of 100. Once you get admitted, none of this matters........after the hurdle of admissions, everyone is equal again and college/academy life begins.
I hope it works out for your son......if he does re-take the SAT, just tell him to relax, get a good nights sleep, don't over think it, don't study for it...just give it his best shot!
