I cannot predict results for Grinnell. We live way to the east of Grinnell and we didn’t consider it (although perhaps we should have, it is a very good college).
However, this uptrend is likely to help you a lot. It will help with college admissions. It will also help you to be prepared to do well once you get to college. Congratulations! In the end the effort will have been very much worth it. Best wishes.
