<p>thank you all, now I understand more about the system. I am sorry I made a mistake in my question - it should be: " there are some other suburb schools in good neibourhood, with very low low income rate …"</p>

<p>Well, in some states, the minimum state requirements for college eligibility are no requirements to enter the open admission community colleges.</p>
