Looks like you need to carefully run your numbers, and see what it is that you can afford to pay. Then you have to be straight with the kids. Transferring OOS to U of MD makes no sense when there are in-state options that are going to be much more likely to be affordable.
Also, what, exactly is sooooooo very much better about a degree in Microbio from UW instead of OHSU? You need clarity on that.
