Como dizer "Vestibular" em inglês

"Vestibular" is a specific contest we have in Brazil, so you may try on explaining the whole qualification process

Vestibular = university entrance exams
Pré-vestibular = preparatory course to pass the entrance exams
Concorrêntes = contesters/ rivals

Como usar:

1) She'll take the college entrance examination. (Ela vai fazer o vestibular.)
2) He's taking a preparatory course. (Ele está fazendo "cursinho".)
3) There's a lot of competition. (Tem muita concorrência.)
4) Competition is intense. (A concorrência é alta.)

Boa sorte!

Crieio que uma adaptação para vestibular poderia ser "SAT" que é o exame parecido que eles fazem lá.

College entrance exam (AmE), university entrance exam (BrE)

Mas eu vi em um episodio do Gossip girl eles usaram SAT.

Hi, guys! I have a further question: How can I say "passar no vestibular"??? I really appreciate your help!

Being "vestibular" a test, I guess you can use the same collocation:

To pass the test
To pass the vestibular

Não passar:
To fail the vestibular

entrance examination

Example: Two-day university entrance examinations begin across Japan.

In the USA, Anita, it would be more likely to hear "I received a high score in the SAT" or "I received a SAT score of (number of points)." SAT is one of several different nationally recognized college entrance examinations. You take the exam once, and the results are given to the universities of interest to you.
