Sorry for your deferral; unfortunately you will NEVER know why. If you were to contact admissions and ask them directly why you were deferred, my guess is that you would receive the standard reply: “We liked you, @ahmedsheta, otherwise we would have rejected you! But we wanted to compare your file to a larger applicant pool, which is why you were deferred.” And that kind of response is not helpful.
FWIW: Colleges judge you in the context of your school and your country. If your school does not offer AP classes or research opportunities, Admissions does NOT hold that against you. So I really doubt it had anything to do with high-quality academic work – after all you self studied for AP courses and demonstrated a self-driven love of learning!
My guess – just from reading this post and your post history – is that Admissions might have concerns about your “character” as the “tone” of your writing comes across as someone entitled, someone who thinks they have figured it all out – and Admissions doesn’t respond well to that. They look for students who demonstrate vulnerability, likability and the ability to be empathetic with their fellow classmates. And truthfully, none of that comes across in any of your College Confidential writing. The other reason you may have been deferred is that Harvard only admits, on average, ONE STUDENT EVERY FOUR YEARS from Saudia Arabia. In a previous post you insisted it didn’t matter because you were Egyptian, but as I pointed out to you, Harvard doesn’t consider your ethnicity, just the country you’re applying from, but you kind of glossed over that fact. See: http://www.hio.harvard.edu/statistics. So, in reality, there quite a few reasons why you might have been deferred.
As others have said, there is NOTHING you can do to fix this situation. Absolutely nothing.
If, between now and mid-March, you have any significant updates to let Admissions know about, you can certainly update the portal, but as 97.7% of deferred students are NOT accepted in the RD round – it’s time for you to move on, and embrace colleges that want you.
