Crisis of writing correct English.

At the very outset I should  honestly admit that I am neither a student of English   literature nor strong in English.Still I feel
I may express my experience. Sometimes past I noticed an important news in a Bengali daily that the primary teachers should be given training how to teach teach English.
It suggests that basic weakness of English lies in the primarily level.

It is obvious that if the basic weakness is not repaired and  the same will automatically continue.

Let me come to the real picture.
My experience is very sad about writing correct English. I have come across a good number of graduates who unfortunately can not write a  single line in English correctly. It is surprising and disappointing as to how they obtained their bachelor degrees. It should be ascertained the reasons for such weakness and the requisite steps may be taken  from primary level of education to college.

One thing I may clearly mention that the graduates about whom I discussed they are all from  Bengali medium. At the same time I have also seen some students despite they are from Bengali medium they are capable in writing correct and good English.
