using analysis board is like using a calculator

Using analysis board is like using a calculator in daily chess. Do teachers give permission to their students to use calculator while giving their math test in school? Certainly not.  So,  why then the analysis board feature is implemented in daily chess. I have a feeling that this feature help somebody to take an easy road to success in internet chess. It gives the players chance to think that they can do the same thing in school.  But this contradict the notion,  since we are not allowed to use calculator while giving math test in school. So i think uses of analysis board in daily chess don't  make sense.  Yet the majority of players including me uses it to play daily chess to my astonishment. 

Daily chess isn't a test. It is correspondence chess which has always allowed self-analysis using another board to test out lines and use as an analysis aid.

And further more, When calculated 3*4 with a calculator, you get the right answer unless you simply don't know how to use a calculator. The same is NOT true when using an analysis board.
