<p>I am a Korean studying in a military high school in U.S.A.
I have applied to Cornell, Harvard, Columbia, Stanford, Johns Hopkins, UMichigan, UCB, UCLA.
Basically very selective colleges. </p>
<p>I am normally staright A students with maybe a B until my junior year.
This senior year in the first semester, I guess it is due to the seniorities, I have attained half Bs and half As in all AP and dual-enrolled classes. </p>
<p>This second semester, since I exhausted college level math courses up to sophomore level, I decided to jump to a senior math course at Florida Institute of Technology. My grades were between C and D. So I eventually dropped that course since it was too challenging for me, and my transcript says "Withdrawal". What I am worried is I am only taking 4 courses this semester of which nothing is related to my intended major - engineering (I am taking AP Gov, AP literature, and AP Environ). I do have a couple Bs in these classes.</p>
<p>This transition of my "straight As" until junior year to "Bs and As" senior year as well as the transition of my very strict and concentrated courseload to somewhat laid-back courses concerns me. Also, I indicated I would take two challenging math courses on Common App in my first semester, and now I am taking no math course at all. Am I being paranoid for being worried about my acceptance being revoked if I get into Stanford, Harvard, or Cornell?</p>
<p>I am quite serious here, and I desperately need your advise</p>
