in portugal between the last 3 years of high school (10º 11º and 12º)
you have to get a good average (its between 1 and 20)
in the 1st period of school i though i had like 13 which is "meh"
but actually i had 15 lol (14.8 to be exact)
but physical education (educ fisica) didnt count for the average in the 1st period so i could have better :P
