Spinning my life events into academic potential - Letter of academic intent [12]
The experiences you describe will make you a very attractive candidate to liberal arts colleges and to universities in general. You may need to tailor your letter to each school, highlighting the ways that what you have and want matches up with what they offer and want from students. Some schools have peace studies programs or cultural studies programs that especially look for students with your kind of curiosity and experience. Any school with a non-traditional program will also find your initiative and courage attractive.
Indeed, these qualities -- curiosity, courage, initiative, real-world experience -- are strengths that you should highlight even when applying to traditional programs. Many students take time off between high school and college. Most drift. Some do career-oriented work that serves only their own self interest. Very few take themselves to war-torn regions or go on humanitarian missions.
I'm particularly struck by your decision to go to Egypt, to get the other side of the story, after living for some time in Israel. This speaks to not only to your intellectual curiosity but also suggests a sincere wish to understand all sides of one of the most vexing disputes of our time. It also shows what kind of person you are. You didn't just take yourself to the library or go online to read about it: You took yourself to Egypt to see for yourself.
See how I've been singing your praises? This is how you want to present yourself. Start your letter with your strong points, and cover any weakness in your high school grades later, giving some reason, however obliquely stated, if they are really much lower than your abilities. By that point, the combination of your writing and your remarkable experiences will make the reader believe that those grades do not reflect your potential.
Good luck, feel free to ask further questions or post drafts for feedback, and don't forget to do your part on the forum by offering your advice to others!
