Hello everyone, I am currently applying for graduate school in the US. I am applying to 10 Schools, 4 have options for waivers, but the remaining schools don't. Summing up their application fees is around $500. I really can't afford this but I want to attend graduate school. Does anyone know any platforms, organisations that I can apply to that can come to my aid as deadlines are approaching and this is the delaying factor. Thank you
