Open book exams

Hi everyone.

My name is Joe. Last year i had one open book exam. I really hate it. Its too tough man....I dont know why university has open boox exams.... for law students and statistics students its good to have these exams...but why us. professors also set very hard paper. I think that their should be some kind of rule that student can opt for open and closed book exam. what you say ??. Last year when i was giving this exam i did not get time to see the book in just 2 hr to complete the paper...It is a open book but guys you won't get time to see the paper and secondly paper is too tough. I think univ should not have this paper.

PLZ give your views...!!!
