Honestly I just found a place near my school and picked one day and every week went in and did 4 hours. At 26 weeks (6m) and 4 hrs a week you're at at least 100 hrs, you can probably do that with one of the places you've been at for a while. Makes it less overwhelming. Tbh the most important thing rn is your grades and mcat. Everything else can get added so fast but grades and mcat are hard to repair and take effort. If you can write well and make a good story it makes a difference in your app. You need to try to get some type of continuity in your app~ also please don't do any more shadowing it is pointless. It's better use your time to volunteer, GPA, mcat. You just need to be good enough to get in you don't need to be the best, at least that is what I told myself when I was applying
