There are a few programs in Neurology which ERAS lets you apply to as categorical or/and advanced. If you choose categorical and advanced, does it charge you like it is two programs?
no.
i did this on several programs and was concerned about the same thing (however at the end of the day I'd rather pay more $$ now, and have better odds of getting interviews and a residency).
Good luck!!
Be aware that there are some programs that are listed as advanced on ERAS, but are basically categorical. Rush in Chicago is an example. They guarantee you a prelim spot there, but you have to apply to Internal medicine separately. Just wanted to throw that out there if people didn't know that.
