Will greatly appreciate any input regarding my question 
If you are a current student who has gotten in with less than 3 SAT subject tests in the RD round, please feel free to chime in. Thanks so much everyone

Georgetown “strongly recommend[s] that all candidates … submit three SAT Subject Tests scores” regardless of whether “they take the SAT Reasoning Test or the ACT.”*
When an admission office makes a strong recommendation, it generally means you risk an adverse consequence if you don’t follow that recommendation. So, you should make every effort to submit three SAT Subject tests. Otherwise, you might inadvertently send the wrong signal.
These rules, however, differ somewhat for Early Action candidates. Thus the Georgetown website states, “Candidates applying under the Early Action plan who have not yet taken three Subject Tests should still register to take the tests in the event they are deferred from Early Action to Regular Decision.”*
Keep in mind that Georgetown will take special circumstances into consideration. Thus, “If there are extenuating circumstances which prevent an applicant from submitting three SAT Subject Test scores, the applicant should provide a written explanation to the Committee on Admissions to be included with the application.”*
I know, for example, a regular decision applicant who applied to Georgetown with only two SAT Subject Test scores. She wrote the admissions office to explain how she was hospitalized on the date she was scheduled to take her third SAT Subject Test. She was admitted and spent four happy years at Georgetown.
Good luck!
Why can’t you take 3? You can still take the Subject Tests in December. Why put yourself at a disadvantage?
I’m not sure why my above post appears with cross-outs. Perhaps it’s Russian hackers.
