Aamir Ali Abro has explained it very well.

In addition to that, you are supposed to fulfil the demand of the question while keeping in view the time not the length of your answer but try hard to provide a concise answer in order to save your time. Time management in this paper is one of the challenges. If you study the questions of the previous GSA paper, they ask questions in a question, therefore, all you need to do is to provide answers to all the areas of the asked question. Math portion might be tough and out of your mind, practice them at the end of the page but must provide the answer according to your perceptions, do not leave any question unattempted.
