So does everyone nees to raise objection of will everyone benifit if only one person raises it
In most entrance exams, if one person raises an objection to a question, everyone who took the exam will benefit if the objection is upheld and the question is deemed incorrect, meaning all candidates will either get the marks for that question automatically added to their score or the question will be dropped from the evaluation completely, regardless of whether they raised the objection themselves.
You need to stay connected with other fellows or candidates who are giving same exam so you all can mutually decide who is going to raise objection if one is going to made then there is no need that all candidates should again raise objection.
Hope you get it..
