I read that there is a new Mendoza policy about the being pre-approved thing, but I was wondering if it’s possible to switch to Mendoza if I ask admissions now or be I guess placed on a “wait list” if pre-approved Mendoza students switch to another school within ND?
I believe that you will be able to apply next year if you attend. Obviously not everyone who is pre-approved will decide to go into Mendoza, so there will be open spots. You can read a little about it here: http://enrollmentdivision.nd.edu/mendoza-admissions-policies/
I believe there was a longer section I saw that you had to submit a teacher recommendation and other materials after your first year, but I am sure you could find out more about it.
