Brazilian big tests

Brazil have a lot of big tests, but it happened a 5 years ago. Today, if you want to enter in a public university, you must take a big test called ENEM. This is a big test that all the country can do. There are two days of test, on a Saturday and Sunday. It has 180 questions and you do 90 questions in each day. The first day you have 4 hours and 30 minutes and in the second day, you have 5 hours and 30 minutes. The second day have more time because in these day we need do write an essay. For ENEM, all that you need do is study a lot. The TEST is long and you have one year to prepare yourself. You need study History, Mathematics, Portuguese, and the other base subjects. Other big test, that happen every time, is the public tender. This test is different and the number of questions never is the same. We do this test if we want to get a job in the government, such as teacher, police, and a bank. This is a very difficult test. Some people pass 5 hours of the day studying to the test.
