you need to have 2 LOR who will fill out the reference form that they supply with the secondary. It states taht they will not accept any other form of LOR. It sucks cause the form is a bitch to fill out so you'll have to ask people who would be willing to spend that kind of time on it. THe good thing though is that it can be anybody. I met with an advisor there and they said you could ask a neighbour (doesn't have to be a prof, or doctor)...as long as its someone who can vouch for you
