<p>Well, all the things she said is true, isn’t it?
Just joking, of course. ;)</p>
<p>Why not ask your mom to join CC and she will be so busy reading threads, she won’t have time to nag you. 
In the mean time, she can check out Hidden Gem schools threads for you to consider and widen the net.
She will understand it’s crapshoot and lower expectations.</p>
<p>This journey is a partnership between you and your family. You need each other to help, not stress each other.
Ask her to help you on this process. Citing meaningless statistics is not helpful. </p>
<p>Give her something productive to do or come up with tasks together (will you be visiting schools over summer? plan trips together. have her look at course catalogs.) so she feels empowered as it seems that she is worried and she wants to help you but doesn’t know how.</p>
