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.
