Colleges in Kolkata

First of all, will you be specific and what do you mean by saying "campassing in the plea”?
Other than that, search for institutes where the criteria is 50% marks above, since your +2 marks is 57%.
Also, there are organizations where candidates with 50% marks and above get a chance to be recruited.

Yes, of course, it depends on your hard work. Good luck.

What have you been doing after completing you 12th? After a long gap I would advise you to go for a regular degree as the quality of education and value of the same is better than that of the distance course.
