ENGLISH CLASS ¿ARE ENOUGH?

¿Are enough the English classes for the students to learn the language do they other things?
Many students are passing the different English levels but they say that they don´t feel prepared for a big exam. That´s an enormous problem because the students fail the final exams and many of them have to go to an English institute or have to do some courses to be able to graduate.
The last years the English classes in Sabana University have been simpler than before because tree years ago many people lost the subject and in those days the English class was added by the average. Now a big percentage don´t pay attention to this requirement.
It is incredible how the students pass the English levels and after that they admit don´t know important grammatical structures and other things that it´s supposed that they should know. The principal cause of this is the little importance that the students give for it but is a problem with English classes´ intensity too.
The problem is that the people don´t take seriously these classes because this it doesn´t affect their academic performance. The people wait until final semesters for put at day the course. It is true that the English language is difficult for many people but the university should demand the English classes. Other possibility could be that the English institute put signs in the whole university like in the airports, in this way the students feeling more acquainted with the language.
In conclusion the problem is that the students’ don´t have enough contact with English language in their daily life and the university English classes aren´t enough.
