    Hi Guys,

     
    This is Biplab from Kolkata, I have attended the SAIL exam for Computer science on 12th December, 2010. In gyst I felt that the questions for technical (section -1) and general (section 2) both were very easy. However the time management is very very important to attain atleast 4/5 of questins. I don't remember much of the questions and here I am listing few of what I can recall. Appologies as not having the accurate sentences as given in paper and any typos
     
    Technical (Section 1) 100 marks, 0.25 negative for every wrong answer.
