Why 33 is a pass mark in Bangladesh?

In 1858, the first metrical test was introduced on the subcontinent. 

But the board authorities were confused about how much the pass number would be and a letter was written for consultation in Britain.

The number of local students in Britain was 65. 

At the time, there was a common concept in English society that "the people of Subcontinent are half as intelligent and efficient as compared to the British" meaning "the people of this subcontinent were considered half as english with intelligence and skill"

In this sequence, the metricison pass number 65 is set at half of the 32.5. From 1858 to 1861, the pass number was 32.5E. In 1862 it was increased to 33 for the benefit of the count. Since then, this 33has has been running.

What's remarkable is that almost two centuries later, our education system has not changed in the history of the 33rd century.

This means the English left us with a fly-by-the-mouth kerani, and we're still basically there. 

If you have a little bit of a head, how can a wise man or nation commit such violence in the 20th century with a personal belief - a great country like a whole India, behaves like a divided core monster? 

United India could have been a rich power in the world today!!
