Yes, it's actually much harder. But the final results are group by category order by rank. There is negative marking to discourage guessing, so the cutoff for certain categories can even be 0 or even negative
So you could make the cut (be considered a successful exam taker) with a zero score just because a large proportion of your peers got negative scores?
This seems just as unhelpful for deciding who to hire or who to allow onto a higher course of study as the campaigns we have seen on some USA university campuses to give all students an automatic A grade.
Note that the system also has many holes, so the categorization isn't perfect. Its possible for a large number of students to belong to the categories only on paper. So you don't even get equity in the end.
