Just a high school student struggling to find a future.
  1. Be an absolute child genius.
  2. Be born into a family that already has alumni from the college. Perhaps a famous one, too.
  3. Assets from family to let you enter a private, selective high school. Maybe it's just as prestigious as the uni/college of your dream.
  4. Over-achieved in all your classes. Score near perfect score in tests. Volunteer, clubs, revisions, repeat.
    Either get A* all around, or 45 points in IB (even more difficult). Then, you MIGHT get a shot at admission.
