Then we agree that even the smaller, extra amounts awarded for scholars, as opposed to finalists, especially when they stack, can still be a nice source of extra funds. Every little bit helps.
I think the reason you may be confused is that you misunderstand the reasons the distinction between finalist and scholar awards is being made here. First, there are many who believe the larger university awards are the NMS awards, when they are not. Also, as was mentioned before, there are extra, often stackable, awards for scholars that are not detailed anywhere on university websites. For example, the extra stackable $1k per year at USC, for a total of $4k, is absent from their literature. There was talk on this thread along the lines of turning down the NMSC $2500 award if a scholar award at a university was more than that. However, one poster pointed out that if that happens, USC would not award the extra $1k per year. Another poster suggested her kid might turn down a corporate award because she wanted to make sure her kid got the bigger award(s) at NEU. The bigger awards at NEU are for finalists, and the corporate awards are for scholars, which stack. Turning down a corporate award would have meant losing a good amount of scholarship funds for that family. So, as I said before, the distinction between scholar and finalist awards can sometimes be important.
