Opinion of the exam

I agree with the exams because is the best form to the things, to see the level of the studient.
The exams are necessary, because the people learn in class, is true, but other people don't listen in the class and never learn.
The exam is an obligation, and to pass and lern a lot of things.
The people don't consider important the exams, because they say they are very difficult to pass.
I believe it's true, because, sometimes the teachers do not give importance, and the people don't know this unit, and the people don't pass.
The importance of the exams is a good thing, but sometimes, it is too important. There is a lot of work, and this work is not evaluated, and this a had thing.
In conclusion, if the exams don't exists, the future will not be safe, and the majority of people will be illiterate, a lot of topics and works. and this isn't good for the society.
I think that the person who knows a lot of things has more possibilities to survive in this world.
