Today, all competitive exams are Multiple Choice Questions(MCQ) based examination system and the main factor is to answer each question in a prescribed time. So, practice as much as possible before the original test you are going to face.

Total number of Multiple Choice Question (MCQ) is 15 and time allotted for each question is 30 seconds. After the allotted time, the question will be marked as un-attempt.
