One Ayala/Dela Rosa to Makati Elementary School

Hello! Scheduled ako for CSE at Makati Elementary School, any ideas how to get there pag bumaba ako sa One Ayala or Dela Rosa? Dun kasi nadaan mga bus na galing sa Area ko eh

As much as possible ayoko mag Angkas/Grab para makatipid. To add lang, Sunday schedule yung exam and call time is around 6:30 so maaga talaga.
