#diss proposal

I’m currently in my final year studying BA History and Politics, and am in the process of applying for a scholarship to study MA History of Medicine. For the application I need to write an diss proposal, it only needs to be a side of A4 and I have some ideas but no idea how to tell if they have potential or where to take them from here. If anyone has any advice or experience with these sorts of applications or with the field it would be amazing to run some ideas past you. Thanks!
