Por la noche, mi novio ya había antes de yo llegar a casa (salir).

The correct conjugation of the verb "salir" in the sentence is:

- Por la noche, mi novio ya había salido antes de yo llegar a casa.

Explanation:

In Spanish, the Perfect Tense is characterized by the ending in the principal verb with "ado" or "ido" (as the exercise where the verb "salir" is conjugated in "salido"), in this case the auxiliar is the word "había", that in English is had, when you see words in Spanish as he, has, ha, hemos, han, había, habías, habíamos or habían, you'll know that the tense is present perfect.

answer:   i cant   remeber exactly but i just got out of spanish a few months ago and the dbas are really easy. just relax, and have your notes in front of you. they are going to ask you the basics study the notes you wrote and you will be fine, make sure to really study grammar and pronuciation. the spanish teachers are usually nice so if you mess up they will go easy on you. you got this, you did the lessons and tests just focus and dont overthink the process.
