There is an ongoing debate regarding whether formal 
 should be held just by using pen and paper. Whilst cutting-edge 
 are appearing day by day, we might need to reconsider what and how the tests should be. In 
 essay, I will explain the reasons why I believe that 
 long-lasting convention is not suitable for modern society.

 means that if we ordered test-takers to equip 
 camera in front of the monitors, we would be able to find

 cheating behaviours and prevent those actions. 
, some people argue that  examiners have many opportunities to supervise actual tests, so their detecting skills are better than those 
 things. Certainly, their skills have been great and effective in the past decades, but it has been proved that the detection rate of the nano-camera is comparatively higher than that of human eyes.

From 
 information, it can be implied that test-takers can utilize not just ordinary equipment, 
 as paper and pencils, but 
 some novel devices, including computers, smartphones and tablets, as long as that camera is installed into them.

 digital transformation indicates the possibility that we can take any test from wherever we can access the internet.

 taking exams and to obtain some hints or answers. 
 is true because the camera itself will be attached to the monitors and cannot check the monitors themselves. Notwithstanding, some applications, which were created only for

, thanks to these technological enhancements, by combining these two inventions, we are currently able to assess educational achievements more flexibly and accurately than before. 
In conclusion,

 are not the most effective approach to evaluating educational performance so far.
