Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

counter clockwise and clock wise direction denotes only sign. counter clockwise direction is positive direction and clock wise direction is negative direction. means sign of ans change only .
why and how does sign matter?
in vector calculus direction have importance.....anticlock wise direction always consider as a positive direction....if in qus they say find ans in clock wise direction then we have to multiply final ans by - sign
but you did not answer the why behind sign?
