<p>I second Chedva. You should educate your mother. But you need to realize it is a negotiation. Your mother told you she would TRY to support you no matter what at your top choice. That doesn’t sound to me like tuition is not an issue. Have a discussion about what she can/is willing to pay. Then start looking at options. LACs can be better choices if you have a good application package (grades/scores/ECs).</p>
