Tufts doesn’t offer Finance or Marketing as majors, so I don’t know why it’s your dream school. Ask yourself what it is about Tufts that appeals to you, and that will help you in finding less selective schools that will suit you.
But honestly, you’re putting the cart before the horse. When you have your test scores in hand; have some handle on the type of school you prefer (big vs. small, public vs. private, co-ed vs. single sex, religious vs. secular, etc., etc.), have determined the location you like (distance from home, climate, big city vs. suburbs vs. rural), and know how much your family will be contributing to your costs, post again, and you’ll get some fine guidance.
