The best ECs are the ones the student is totally into doing for him or her self not to get into a good college. It is not worth it to try to game the college admissions process. Students should go after the activities that are meaningful to them. They should take the courses that are meaningful to them and which the student things will be helpful for developing into the kind of person he or she wants to be. Then, when it is time for college, the student will match with the college that also views the activities and classes the student chose as being the best ones to have picked.
