<p>If you search the web sites of various colleges (try “GED admission” for a start – it should lead you at least to the common data set), you can find out if they accept the GED. Some colleges do, some do not. I think the more competitive places do not, but I haven’t studied the matter.</p>
<p>Realize that the GED may or may not substitute for a high school diploma; it wouldn’t substitute for required courses. I don’t think a selective place is going to go for someone with a high GED and SAT without documentation of any coursework. You might be able to work your way around this with SAT IIs, CLEPs, use of the ACT instead, etc., but you would have to ask.</p>
<p>I also am unclear about your educational background. Did you attend a school but didn’t graduate, did you learn at home but failed to comply with state homeschool requirements, or what? It is difficult to give advice without knowing.</p>
<p>As has been already pointed out, you can always contact potential schools, give them your details, and see what you will need to be considered. Without knowing more, I think your best bet would be a year or two in community college and then transferring.</p>
