I had a hard time navigating AMCAS's activities' section due to the freedom I had in regards to what I can do with it. Especially there is no instructions or recommendations on formatting on this section, which makes it even more confusing. You can enter up to 15 experiences and activities with option of choosing up to 3 of them being the most meaningful to you. When you pick the most meaningful experiences, you can to write more about it in the extra space.
Did I use all 15 entries ?
I entered 15 activities including clubs, scholarships, awards, volunteering, posters, tutoring, research, conferences, shadowing etc. I personally used all 15 activities, because it gave me an opportunity to draw a picture of myself to readers. You do not need to fill all of them out if you do not have anything relevant to say. If you enter irrelevant information, it might actually annoy the readers.
How did I pick my 3 most meaningful experiences?
I picked 3 most meaningful experiences, because it gave me more space to let admissions committee know more about me. I entered short essays that I wanted to mention in my personal statement, but could not fit. I picked three activity that represented me the most. There were research, non-medical volunteering and physician shadowing experiences.
What did I include in the descriptions?
I used a formula of a brief description of an activity followed by a description of what I learned and how it relates to medicine. It is important, because it is med school application after all.
Did I group similar activities?
I grouped my shadowing, volunteering and scholarships/awards into single activities respectively, so there is no redundancy. I used myself as a contact, if the school needs more information, they can contact me for a specific contact information, which is the recommendation by AMCAS anyway.
What format did I use in the description?
I used very concisely written full sentences.
If you have any more specific questions, let me know, I can add onto this post.
