Tier-I Examination: The First Hurdle

The Tier-I examination serves as a qualifying stage for Tier-II. It is a computer-based test consisting of objective-type, multiple-choice questions. The questions will be presented in both English and Hindi, with the exception of the English Comprehension section. A negative marking of 0.50 marks will be applied for each incorrect answer.

Structure of the Tier-I Examination

Subject	Number of Questions	Maximum Marks	Duration
General Intelligence and Reasoning	25	50	1 hour (1 hour and 20 minutes for eligible scribes)
General Awareness	25	50
Quantitative Aptitude	25	50
English Comprehension	25	50
