[dimasahmad111]

Hi, anyone know for courses that provide live a/b testing case, i want to learn but most of the courses is just basic things, not real experiences also bit confuse the different between a/b testing product and digital marketing:

1. what to do
2. what to test
3. how to plan
4. how to test
5. etc

if you have an experiences at professional level, i am happy to learn or 1-on-1 with you.
