I NEED HELP

Hi so im tring to understand the apostille processes i think i messed up everything changed.

So i want to apply to Sejong university, Hanyang, Korea University, Sogang University, HUFS and Konkuk University.

I already legalized my documents and translate them now i have to apostille them expect thats its 1000€ like wtf ?? i already paid 500€ the translation so i can not pay 1000€ for apostille.

I think i didn’t do the right order for my documents that i should have apostille them before translating them 🥲 but now idk what to do and what i have to apostille i have to apostille all of my french documents right ? like birth of act and divorce paper of my parents etc etc etc please can someone explain to me what i should do or what i should have done.

And for the apostille if im applying for 6 university and i have 13 documents so i have to apostille 13 x 6 documents like all of them the 78 documents right ?

ps : its for undergraduate admission so im doing all on my own
