This reference is priceless, and you will realize its importance while filling up the AMCAS application.
An applicant can include up to three experiences in the work and activities section of the application. He/she must choose the most meaningful experiences that will go with the profession. They should include the experiences that affected them the most. So, take time and think about the experiences carefully. If you have a journal, it will help you write the detailed description of your experiences quickly and more correctly.
