Better way to prepare for PH test organized by elitmus?

Few questions of the pH test organized by eLitmus are always gets repeated sometimes exactly or the data of the question will be same.Practice previous set of questions more and more.Moreover the cutoff marks of the test to get 80 percentile and above are somewhat less in some sections likeFor Aptitude and Logical Section it is like 5 - 10 questions.So the most important fact is you have to attempt few question that you know with 100% accuracy, because negative marking is there.But for English section cutoff marks is higher, so I will suggest you should attempt as much question as you can.All the best.
