Just create a google sheets. Add columns of interest - whether school name, size, city. Obviously one column will be admissions deadline. Another scholarship deadline. One financial aid deadline - or go school by school and figure out…so and so may have a January 1 deadline but Nov 1 for scholarship. So then Nov 1 is your deadline.
Slow down….school by school…make sure you have the right info - before moving on.
Then sort your sheet by earliest to latest date.
