Someone mentioned it earlier in the thread but I think you may have glossed over one point. Assuming you are correct and you are certain to get a scholarship, there is no guarantee that the scholarship will be to the school you are applying ED. If you apply ED to JHU and then get awarded a scholarship to another school, you will have a complication. You can try to get your scholarship transferred, which as I understand is tricky when your school is an expensive private university. Other options are to try for a college based scholarship or go through the first year of ROTC without a scholarship and apply for a three year one while you are a freshman.
My point is only that your decision tree might be a little more complex than you think. Good luck.
Absolutely correct!
A few things that may stand in your way of getting a scholarship...
1) JHU is a high cost private school. Often there are few if any 4-year scholarships to these institutions in any given year. Sometimes the only scholarships are 3-yr AD (you pay for freshman year).
2) You may have great stats, but ALL the applicants for JHU have great stats. And you WILL have competition for those few scholarships. And you mentioned that you cannot visit the campus. The cadet who has great stats AND does his/her interview with the PMS there is more likely to get the "green light" from the unit when Cadet Command looks at the unit's preferences for scholarship recipients.
3) Applying ED does increase your chances for admission. However, you had better be aware that JHU does not guarantee that you will like your financial aid award and when you commit ED, you have agreed to withdraw all other applications upon receipt of admission and accept their offer regardless of what you think of their FA package. And if AROTC doesn't come through (see above), you could be setting yourself up for a lot of financial problems. Understand the rules for accepting and possibly withdrawing (you can before a certain date) ED applications along with the AROTC board dates before you get too far into the process. You CAN apply ED and possibly know your first board status before the ED withdrawal date, but each year is different.
4) There are plenty of opportunities to go to Grad school while serving. One in particular (GRADSO - do a search for it) allows you to take 2 years off (while collecting pay) to attend a school and degree of your choice that you have been accepted to fully paid for by Uncle Sam. This takes place typically after your 7th year and requires an additional 6 years of service. There are also opportunities to go to med school (search the forum for more details) as well.
5) Now the interesting detail that most HS students don't understand about advanced degrees. It isn't necessarily the guy going to the top rated Undergrad school who gets the best grad school opportunities. It is the guy who has great grades (JHU is UBER competitive), great test scores, and great professor recommendations who get into the top grad schools. The best way to get great professor recommendations (and undergrad research opportunities) is to be the top student. The best way to be the top student is to attend a school where you are in the top 10% of admitted students. Your 4.7xxx GPA and NMS credentials barely put you in the upper half of JHU admitted students, I'm sorry to tell you.
6) And talking about qualifying for GRADSO, that is given to 4-year (not 3-year) scholarship winners first, by OML which is heavily based upon your college GPA as well as a long list of other things (ECs, varsity sports, leadership positions both inside and outside ROTC, etc.) The Army doesn't care where you get your undergrad. A 4.0 from bi-directional state U is better than a 3.9 from Harvard.
What I am telling you is that you can get a great education at "lesser" schools than JHU, increase your odds of getting a AROTC scholarship (public schools get many more), make yourself more competitive academically for grad school, improve your OML and chances for grad school opportunities - all the things you talk about. Just do a bit more research here and at sites like College Confidential and you will learn that there are sooo many variables in getting ahead.
I actually appreciate your confidence (even if it comes off as cocky). Just remember that you are one of thousands of similarly (or even better) qualified candidates. Seek out a strategy not to fulfill your ego, but based upon what works for your goals.
