There. Have this as an excuse for me needing your help.
This is a german YouTuber for CharleySenpai s contest.
The name's MythosOfGaming.

Now that that's done, please help me. I got a French exam tomorrow. And I'm doing last minute studying here. If there's anyone out there who can help me:
When do I have to adjust a verb whose builds its past tense with avoir? Like être, whose past tense would be avoir été. In which phrase composition do I have to adjust it (with -e, -s or -es. Ya know?)

Please help.
I got a bottle of coke and it's 10:30 pm. I'm ready for a whole night of studying.
