Shot down as a freshman, probably not in as a transfer, best school to transfer to..?

<p>I didn't apply as a freshman since I slacked off in HS (I'm a senior now). I know that the college I am going to attend (got into OU, KSU, Union College(ny) and deferred at OSU) won't be able to help my get into MIT as a transfer, so my question really is, what school should I transfer to so that when I apply for grad school (in physics or math most likely) I will have a much high chance.
26-ACT (taking again in dec)
3.6 unweighted gpa
In post secondary enrollment classes (already have my freshman year done while in HS)
Taking summer classes as well
Have 200+ volunteer hours not formally accounted for (which i guess means absolutely nothing) And about 20 hours formally accounted for currently</p>

<p>EDIT: *a much higher chance as acceptance into the grad school.</p>

<p>Sorry for the typo.</p>
