Examination system - A Question: Part 1

It all starts at the tender age of 5 or 6 years when a student/kid enters in the classroom for grade 1. After that, there is a span of 15-16 years which the student undergoes with the same monotonous life of class tests, unit tests, yearly examinations and also other than this … projects, homework presentations add only the anxiety and boredom to his/her life.
You must be thinking what rubbish I am writing here… This system has produced the great students who become doctors, Engineers, Lawyers, Reporters or even Politicians. Then what makes me think to raise a question over this ongoing process. Actually what we are watching is only the positive part of this system. We always make records for the successful students of every school, college, university, but have we ever taken any records into consideration for the students who are not so successful after their studies.
For example out of a class of 50, On an average only 5-6 students manage to be above 90%, 10-15 manage to between 80-90%, around 15 in between 70-80% and around 20 are below 65%. This percentage goes on decreasing once these students cross the board examinations. You can always find little more addition to the lower percentage groups. Are all these students that bad or all the high scorers are great enough to do everything better than the Low scorers.
Actually as per my understanding, the answer is certainly NO. What I feel is, these examinations are not the true evaluation of a student’s knowledge. We all know now days actually how difficult it remains to clear any examination… Apart from some good entrance exams; anybody can clear any exam of university level or school level with only 4-5 days of preparation. This means that these examinations are not helpful in terms of knowledge. Securing good marks is the only way which has remained to be achieved, not the knowledge. You can go through the whole material a week before the exams, mug up the contents and can easily secure the higher ranks. But you cannot acquire the true concepts and knowledge for which that subject has been introduced in to particular stream. There is no interest left in students to go in to deep research about the subjects, to explore the subject specified to them. For example an Electrical Engineering student knows that he doesn’t require being great with the heavy machines concepts as he can easily get the job in IT with good marks. So what he does is do short term courses for Electrical content , clears the exams and got selected into IT field through campus selection. So what all he requires from his or her degree is just good marks not the Knowledge.
In the end few Questions arises are
How can we generate the Interest in the students for their respective fields?
And
Can low scorers be benefited more with any other examination system?
