I am inter 2nd year now I have completed to write jee mains paper 2 in that online paper I draw the diagrams but I don't mark that answered

Hello Dear

Since as you said you have drawn the diagram but you didn't marked so in such critical cases your answers won't be evaluated by the authorities since it has not been tick. This is your major mistake dear that you didn't opted the answer because without opting that answer it will not be considered for the evaluation prospective but anyways hope for the best.

All the best
