Topic: Examinations on MSCA: SQL 2016 Business Intelligence Development 70-767 and 70-768

All greetings, colleagues!
Somebody already managed to hand over or can be someone in the course of preparation?
What can advise?
Can be we exchange contacts for joint preparation?
I first of all am aimed on 767, is closer to my current activity, but there are also novel subjects for me from examination.
