What material to purchase for LEED Green Associate

Hi opi. I need suggestion guys. I have research what learning materials to have since I want to be a LEED Green Associate (next is LEED AP after I pass this one). Im a beginner and no subject course from my undergraduate studies.

I look in the USGBC material and I'm confuse from their materials. I want clear reference/materials to review and study.

These are my top 3 searches (NOT IN ORDER):

1. Instructor named Shd1 AS. he got udem and archiroot. but noticed in archiroots he got flashcards + practice exam way better offer than udem. both of them has separate lesson them practice exam

2. gbes. the platinum pack. this one got bundle

3. projectific. this one got bundle
