Exams to the university

I will do the selectivitat at September because I flunk some subjects for May. At my exams to acces at the university I will do a comun part and the optional part. For the optional part I ried Byology, Maths and Earth sciences. The students can choose the third language, too, in my case I tried english, and the last thing that a student can choose was between phylosophy and history, I tried history evidently because I don't pass the philosophy exams.
