      1.   I DN'T UNDERSTAND WHAT'S THE DIFFERENCE BETWEEN SUGGESTED ANSWER AND COMPILER.TO MY KNOWLEDGE,IN SUGGESTED ANSWER EXAMWISE ANSWER IS GIVEN.THAT MEANS,EK SUGGESTED ANSWER MAIN EK HI EXAM KA  SOLVE PAPER REHTA HAI?COMPILER MAIN KYA ALL EXAM KA SOLVE PAPER HAI?

    2.MAIN PCC KAA STUDENT,BUT PCC KAA KOI COMPILER OR SUGGESTED ANSWER NAHI HAI,TO PE -2 KAA COMPILER SOLVE KAR NE SE KAAM HOGA?
