There is no such rules for attempting all the sub questions of a question at one place but its preferred rather than the scattered answers. Attempt the answer which you can best answer no matter what is the order. But dont forget to mention the correct question and subquestion No.
In a CA Exam if answer is correct you will get marks which you diserve no matter in what order you write in your answersheet. Best of Luck.
