If it takes 4 months, then many schools on your list are going to be difficult to achieve from a logistical perspective. Some of those have rolling admission and EA where this might work for you, but many of the schools announce regular decisions sometime during March, and students have to (in a normal year, covid has delayed some deadlines this year) commit by 1 May. Unless I misunderstood how the 4 month timeline works, that’s just nowhere near enough time.
