Pre reqs for BSN

Hello, I am looking into National University for my pre requesites then apply for their BSN program. I am not transferring any classes either. I recently spoke to one of the advisors there after my friend had spoken to her advisor. Her Advisor told her she can do all her pre reqs there in about 13 months and financial aid covered everything for her since she's a single mother makes sense right. Well, when i spoke to my Advisor she told me I couldn't do that and I had to enroll in an AA of science in order for me to qualify for financial aid which is completely different than my what my friends Advisor said to her. I'm very comfused because I have heard of a lot of people taking only their pre reqs there and not having to enroll in an AA with extra classes that are not required for the BSN. Any advice please help ? TIA
