On the other hand on answering questions by writing text you may fail even if you have studied good cause the questions are rather few to cover the material.
It is known how those test should be made, demand that question ought to be representative for the entire subject must be met. Also certain precent of open- end questions should be there, perhaps also one short essay type of question and the rest closed questions with answers that are all to some degree plausible. So, those tests cover usually the complete exam material of 2000 pages via 4 written exams, each with more than 50 questions. It lasts longer but to achieve accuracy and fairness that is OK.
Curiously, being small group of 50 students who were on those exams, usually the rankings (grades of students) were similar from exam to exam, same people achieved more or less same ranks, proves that people who have higher abilities and put more effort were righteously rewarded for both using that method.
However you can get a very high grade deviating largely from average if you study excessively.
Yes, it was hard or impossible to get 10 in Psychology, very rarely, and it meant that person learned the subject to the last detail.
I prefer that system than the one where verbalization and personal contact can contaminate (and they usually do) the evaluation of the student's knowledge by the professor.
I gave up Law after passing Criminal law, general part and when professor told me that she will give me 9, that all facts are told
, but not presented in a way it is expected by future lawyer, then she listed my student book and said that for the same reason other teachers were giving me 8 mostly. She said that facts in law sometimes have less significance than verbal presentation of facts?!, and I told her that I will think about continuing law if that is the case. Then 1999. came and ambivalence was solved. I quit. ( I was on 3rd year, and I was for the second time learning the International Public law, with all the idiotic details about UN and international legal acts, while bombs who flew against those super cute declarations were making whoooozeee, boooooom above my head repeatedly. Then it was over. Thank you good soldiers for helping me become good and poor person, not some filthy rich lawyer)
