I have given drawing part (in jee paper 2) wich is not extrodinary but good how manymarks can i expect out off 100 ??

Hello student. It is hard to expect the mark. And if there is anyone who can really evaluate the mark, then that can be solely you.
Because, only you know how accurately you have presented, how the presentation was, accuracy of the drawings etc etc. All these. You have told that you did do in the scale of average. So if I am not wrong. You should be getting in the range of 40 to 50.
Kindly you evaluate too
