Honestly I didn't check. I just saved it with the intention of framing it later in life to troll my grandkids by telling them it's an acceptance letter.
I'm not having kids, let alone grandkids... but I did keep the Harvard letter also, at least for a few weeks, out of personal amusement. Mine was for the medical school, not the MPH. It explained that they had received my test score and demographics from AMCAS and that based on that they thought that I should apply there. I ultimately tossed it, because why hang on to a piece of junk mail, however prestigious the sender?
I do remember checking a box on the MCAT application saying that they could share my info with schools, so I am sure that is how this info gets out. It happened the year before just after I took the MCAT the first time. My first score was quite good as well, and within a few weeks I was getting tons of postal mail and email from schools.
Back to ads on this site... I just saw an ad for Art Institutes, offering an "art grant" of $18,600 which they identify as 20% of the cost of 4 years of tuition. I consider Art Institutes and Caribbean schools to be very similar in their predatory practices toward students and the likelihood of their students to graduate and find a position in their fields. I cannot tell you how many people I know who are art school dropouts, but I will say that I know a dozen who actually graduated and are now working as artists... sandwich artists. With an average of $100k student loans, they make great hoagies and subs at some of the finest pizza shops in my city.
Carib schools, even the more legit of them, take more students than they can hope to place in clinical rotations. They count on attrition, natural or forced, to trim the class down. Then, their few graduates enter into a competitive residency match process where they are already at a disadvantage from the start. You may emerge from an offshore school as an excellent doctor, just as some people who went to the Art Institutes are exceptional artists. In both cases, that is entirely due to the efforts of the individual, in spite of the school. If the same person had gone to a real institution and given the same effort, how much farther might they go?
