I love your plan. I also love that you are obsessed with preparing for this application season. You NEED to be obsessed. You need to eat, sleep and breath this obsession. No one is going to be a bigger help in ensuring you get to your right university more than you. I remember my S20’s process and at the time, both he and I could be described as obsessed. You need that obsession to do all the things you’ve done, up to and including initiating this thread, asking questions, considering the responses, and refining your list and process.
Too many students/families just wing it, blindly choose a few schools, and apply. Your high level of research and planning will help you tremendously.
Thanks for the update, and keep up the good work!
