on examination与upon examining 意思一样吗

As students,we regularly deal with exams.There are weekly exams,middle term exams,and final exams.These exams are designed to make us study hard,but do they really work that way?I don’t think so.Many students I know they just study for exams,not for knowledge.Before the exams,they would memorize everything the teachers said to be important,without really understand the true meaning behind it.So they may get good scores on the exams,but they will forget very soon.That is learning without understanding.In my view,I would like to have fewer exams,but make sure that the students understand the knowledge.Well,it may be difficult,but I think it can be achieved with better and more interesting teaching methods.
