Academic grading in Costa Rica

Academic grading in Costa Rica works on a 100 point scale (and sometimes in an analog 10 point scale). For primary school level, a 65 is good enough to pass, while in high school and further levels the pass grade is 70. Students who attain from 60 to the pass grade get the chance to take on one extra test that reviews the whole year's topics, and in which a 70 is needed to achieve a pass grade.
