Paper Model:
Section I: computer awareness(i.e general things about computer)
Q.15
-ve marks -1/4
Section II: Simple C- language Q. 15 & -ve marks: -1/4
Section III: On pointers & structures
and C++,JAVA( only 1 on this) Q.10 each quetion ->2 marks

-ve marks: -1
Section IV: Analytical Q.20 each quetion -> 2 marks.

-ve marks: -1/4

VIJAYA from each section Iam giving one are to quetions also because
for checking whether the same paper or not. And for doubtful
answers also I am writing quetions but not writing
answers for these quetions.

BEST OF LUCK

In written test in each section you have to get minimum marks i.e
you have to pass in each section. There will be questions from
C, C++, JAVA. about 10 questions in C++ in the written test.
