That means there should be 300-400 left to send. Once you deduct the prepsters (200) that leaves 100-200 offers to fill other vacancies. Figure 25-50 are for vacancies held up by medical waivers, and probably another 20-50 were for candidates that finished their files late and are still going through the qualification and admissions committee review but were definitely vacancy winners (principal nominees and clear competitive front runners). So yes, the class may be full if you aren't in one of those three groups...or there may be some more room left yet depending on who has been offered in each nomination category, who doesn't get qualified, and who declines.
It always gets interesting down the stretch...as the acceptance deadline approaches, you'll see more declinations. Some of them are figured by a historical acceptance rate of around 88-90% (ie, if 1000 offers have gone out, at least 100 should decline, meaning there are still 73 sitting on the fence holding onto a spot for 2018 who will ultimately decline). This is where we start seeing ones and twos for appointments in the later weeks from the mid-April decision/medical waiver deadline leading up until R-Day. Hence, needing to make +/- 1375 offers to fill a class of 1250.
