Dear Brother. objective portion is very easy. I made files for each part i.e. for tort a separate file and collected subjective and objective portions then i came to know that most of the questions were repeated. So in this way it was easy for me to solve objective portion while covering subjective one. One my university senior-- now deputy accountant general-- opted law and got 168. he is from 34th common.
So, I can say law is a scoring subject but choice is yours.

regards.
