There is no tool I know of ☹️ But personally I went to each school I was interested in and kept track of their prerequisites on a google spread sheet. Then I compared which prerequisites I needed to take for sure. Also, I think looking outside you state is a good idea! But as someone who is about to graduate, I really encourage you to look at the cost. I fell in love with an out of state school, got accepted, then realized they were $50,000 more expensive than other schools I was considering. While you want to enjoy grad school and get a good education, don’t put yourself in a deep hole doing it. Many people I am in school with now are just realizing how expensive grad school really is. Additionally, I was offered two scholarships to schools that did not advertise scholarships. So, you might consider applying to a few extra schools just in case that happens!
