One disclaimer: go for Pitt, so long as you aren’t thinking of the neuroscience major as a path to a US med school. This path is so inaccessible to international applicants that it would be very unwise to invest in an expensive undergrad education aimed at that goal.
If you’re aiming for an academic grad program (or med school in your home country, although for many countries that would be direct-entry in undergrad) and you can make Pitt work, definitely go for it, and congrats!
