First of all if you are not familiar with the question then I recommend you to leave the question because if you attempt then it will turn into negative mark with 75% chances therefore if you don't know a single thing about the question then the top most priority of you is to leave the question as it is if you know something or you can eliminate some option then only you should try to attend the question there for while attempting the question if you have some idea of the questioner options then only you should try it otherwise don't waste time in attempting the questions which are not known to you .
