There is a chance that if you contact the admissions office, that they will hold off on evaluating you until the latter end of the pool, but they're not obliged to, and considering that most schools that require subject tests are on the more selective end of the spectrum, they likely have a tremendous amount of other qualified applicants who do have their subject test scores already, so just be forewarned that they could basically just tell you that there's nothing you can do about it and that you won't be considered.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
