How To Access An Ipo?????

#1
I am a new investor. I have an account at Scottrade. I have done some research and it appears that IPO's profitable. However, they do not allow access to any IPO's. I noticed other brokerages like E-trade allow some of their clients access to IPO's. I was wondering if anyone knew which brokerage is best for getting in on these IPO's. In addition, there are certain prerequisites to access the IPO's from these brokerages. My friend has an E-trade account. To access the IPO, he had to fill out a form asking for income and trading experience. However, he was denied access to the IPO. I was also wondering if anybody knew what prerequisites are required for your brokerage.
