<p>sonmere,
My D. was on full tuition Merit at state public in-state. That allowed us to pay for her Med. School. But not all schools awarded the same amount, some were much better than others. It is worthwhile to check if you are interested. We could pay, but why if there is a free option? The most important though is to be at place that matches their personality and wide range of interests. So, Merit award was basically a bonus. I still do not see why your S. should re-take ACT, but it is his decision. Best wishes!</p>
