I think the T14 is going to be just out of reach. However, I think you have a VERY DECENT shot at some solid schools outside of that group.
Yes, you will go to law school. And yes, you might even go to a top 25 school if you put some thought into your addendum. Congrats!
Where are you located? Are you interested in any particular region?
The bolded is not necessarily true. Some t14s (NU and to a lesser extent, Mich and UVa) are known to be splitter friendly (though you may have to ride out a waitlist for a bit).
I think it's very unlikely to crack the T14, but I think you're right. Some schools are better than others about splitters, so you never know. I CERTAINLY encourage the OP to apply to a few schools in the T14, absolutely! The odds are against him/her, but it's certainly worth trying. With a LSAT of 172, you definitely have to try. But I do think he has a great shot at some other schools ranked outside the T14, but within the T25, which is good news.
