Hi Willa,
It is great that two good options are available to you. Although different, either way would work.
Option 1 is to try to get in Stanford as an undergrad. It is achievable if he continues to do well but no guarantee given the fact that Stanford is very competitive. Another thing to consider is the cost. Four year at Stanford will probably cost over $200,000. Some assistance may be available depending on income/asset, etc.
Option 2 seems to me a sure thing if your son chooses to do PSEO. The saving is huge. Although going to UofMN is not same experience as going to Stanford, it makes you wonder whether that amount of money is really worth it. Besides, your son already decided to go to a graduate school. That makes Options 2 even more appealing because people usually only look at your last degree.
