Typically multiple choice tests have 3 choices: two wrong (one dead wrong and one that's articulate yet still wrong) and one obviously right.
Traditionally, our grades go up to 20; less than 10 is a negative (fail), 10 and up (rounded, so 9.5) is a positive grade.
Getting into uni may require something like a 19.5+ grade, depending on course (traditionally medicine, lately also airspace) though...
