Opinion paragraph

Our education system has many aspects which I don't agree with for several reasons. 
In the first place, there are some subjects such as History of Spain in which you study all of units you need to pass the exam. When the exam day comes you write everything that you have studied and a few weeks later you don' remember almost anything. For this reason we should look for other mehod in which we study to learn and not only  to pass our exams, like nowadays.
Secondly, I don't understand why they have to do so many cuts, for example:
Last year and  this year too, there are classes at high school where there are so many students that they have to stand because there aren't enough tables and chairs for all students. 
In short, we must do something to improve the situation because this isn't a good Education System.
