In this blog, we have mentioned the SSC CGL Tier-2 Paper-2 (Statistics) study plan for 30 days to clear SSC CGL Exam 2025. To understand the study plan, it is necessary for candidates to have an idea of the exam pattern and syllabus.

SSC CGL Exam Pattern

The SSC CGL Exam Pattern consists of four tiers: Tier 1, Tier 2, Tier 3, and Tier 4. Each tier evaluates candidates’ skills and knowledge through various formats like computer-based tests, descriptive exams, and skill tests. Tier 1 is an online exam with multiple-choice questions, assessing General Intelligence, General Awareness, Quantitative Aptitude, and English Comprehension. Tier 2 is more advanced, consisting of two papers focused on Quantitative Abilities and English Language & Comprehension. Tier 3 is a descriptive paper that tests writing skills in English or Hindi. Tier 4 includes skill-based tests for specific posts. The detailed marking scheme and subjects covered in each tier are crucial for candidates to understand the exam’s structure and prepare effectively.

SSC CGL Tier 1 Exam Pattern

The SSC CGL Tier 1 Exam is a qualifying exam, and the score obtained in this exam will not be considered for the final selection. The details of the SSC CGL Exam Pattern are as follows:

1. Exam Duration: 60 minutes.
2. Negative Marking: 0.50 marks per wrong answer.
3. Qualification Process: Tier-1 is qualifying; Tier-2 determines final merit.
4. Paper 1: Must qualify each section separately.
5. Merit List: Based only on Tier-2 performance.

The subject wise weightage for Tier 1 is as follows:

Subject	Questions	Maximum Marks
General Intelligence & Reasoning	25	50
Quantitative Aptitude	25	50
General English	25	50
General Awareness	25	50

SSC CGL Tier 2 Exam Pattern

The SSC CGL Exam has undergone important changes in its evaluation process and time allocation. The key details about the merit list preparation, exam duration, and negative marking policy:

1. Merit List: Based only on Tier-2 performance.
2. Exam Duration: Paper 1: 2 hours 15 minutes; Paper 2: 2 hours.
3. Negative Marking: Paper 1 – 1 mark per wrong answer; Paper 2 – 0.50 marks per wrong answer.

The subject wise weightage for Tier 2 is as follows:

Session	Subject	Questions
Paper 1 Session I (2 hours and 15 minutes)	Section I (1 hour ) Module I – Mathematical Abilities Module II – Reasoning and General Intelligence	30 30 60 x 30 = 180
Section II (1 hour ) Module I – English Language Comprehension Module II – General Awareness	45 25 70 x 3 = 210
Section III (15 minutes) Module – I – Computer Knowledge module	20 x 3 = 60
Session II (15 minutes)	Module – II: Data Entry Speed Test	One data entry task
Paper 2 2 hours	FOR JSO: Statistics (Paper I & II as above)	100 x 2 = 200

SSC CGL Tier 2 Paper 2 (Statistics) Syllabus

As per the latest SSC CGL Syllabus, candidates appearing for Tier 2 Paper 2 (Statistics) must have a strong grasp of core statistical concepts and applications.
