Good for you, and I don’t think you’re that unique in this regard. Many people want a well-rounded education, including many who go into tech. Many people do not view “liberal arts classes” (like physics, math, biology, history, philosophy, language, economics, etc.) as a burden or some stupid hoop to jump through, but rather as a privilege. Based on my life experience, I advise you to hang on to that.
Lastly, consider need-aware schools in context. Many schools that are need aware are only factoring in need for a small % of the total class and truly are selective. And frankly, who cares? If you like Brandeis over the others, go there. People launch into CS from all kinds of places, and there are several posters in this forum who have CS backgrounds who don’t think the quality of CS instruction varies that much from school to school. Others probably disagree.
