Deciding between High School Online Classes

<p>Hi guys
I've gotten into homeschooling and I'm trying to choose a really good online class program
I have chosen 2 that I really like which are Brigham Young University and Indiana University Online High School
I don't know which one to choose and I was hoping you guys can help
Brigham Young University (the actual college) is rated #62 and Indiana University (actual college) is rated #76. I'm wondering if these actual colleges have any effect on their online high school program. Also, I'll be needing a high school diploma and Indiana University provides a diploma upon registration and that could be a choosing factor as well. I'm trying to get into the top ivy league colleges and I need to decide which online high school program is better in terms of which one is more rigorous and will provide me with an advanced education. As well as which one do top ivy leagues recognize more.</p>
