Even though I have more than 8 years experiences in Drupal (D6 and D7), Drupal 8 is still a brand new platform to me. It is a great opportunity to learn D8 by taking Acquia Drupal 8 Certification Exams. I had passed the Site Builder Exam, and will take the Developer Exam in September. 
I would like share some experiences about how to prepare for Exams of Acquia Drupal 8 Certificated Site Builder and Acquia Drupal 8 Certificated Developer.
1. What I learned from the Certification.
2. Main points to leaning Drupal 8.
3. Thoughts about Drupal 8 Site Builder Exam.
4. Thoughts about Drupal 8 Developer Exam.
