I would say yes. I did the International Bac and got an average grade, 31/45. I am at uni now, i met the requirements to get in, set by the uni. And i find that most people who are supposedly the same level as me are no where near of a similar standard. Many looked scared at the idea of writing a long essay or doing critical analysis of something.
Exams are meant to show a true grading of students. The marking should be changed into %. And then people are given the percentage. And if many people get high marks, then they should make the test harder, to show those who truely are good and those who arent so good.
We will find out that exam marks will of once again increased another year in a row. So they are obviously too easy or too predictable.
