@Samsch6 One idea (though a bit unorthodox) might be, in combination with raising your ACT, taking some Subject Tests and scoring exceptionally. WUSTL does not require or recommend them, but it will consider them if they are strong. I don’t know exactly how strong your Hebrew is, but if I were you, I might look into studying for and taking the Modern Hebrew Subject Test to demonstrate a unique skill. Aside from that, any Subject Test in your intended major (provided the score is high) could bolster your credibility in that field.
This is all hypothetical and far from critical to your application; nevertheless, I might think about it if you can score at or near an 800 on Hebrew and/or 750+ on another Subject Test related to your intended major.
