Age Limit

For most posts, the age limit ranges between 18 and 30 years as of the crucial date specified in the notification. Category-wise relaxations apply as follows:

• OBC Candidates: 3 years
• SC/ST Candidates: 5 years
• PwD Candidates: 10 to 15 years

Educational Qualifications

Candidates must hold a Bachelor's Degree in any discipline from a recognized university or equivalent institute by the cutoff date specified in the official notification.

Application Process

Submitting your application correctly is vital to avoid last-minute rejections. Follow these simple steps when applying on the official portal:

1. Visit the official website at ssc.gov.in and complete your One-Time Registration (OTR) if you are a new user.
2. Log in using your registration number and password.
3. Navigate to the 'Apply' tab and select 'Combined Graduate Level Examination 2026'.
4. Fill in your personal details, preferred exam centers, and educational qualifications.
5. Upload your live photograph and scanned signature as per the technical specifications provided.
6. Pay the application fee of INR 100 online (Women candidates and candidates belonging to SC, ST, PwBD, and ESM categories are exempt from paying the fee).
7. Submit the application form and keep a printed copy for future reference.

Preparation Strategy

Preparing for science questions for ssc cgl tier 1 requires a structured approach. Because science syllabus questions are direct, systematic preparation yields quick results. Here is our recommended roadmap at ExamBhai:

1. Build NCERT Fundamentals

Start by reading Class 9 and 10 NCERT Science textbooks thoroughly. Pay extra attention to highlighted terms, summary tables, scientific laws, and chemical reactions. For instance, understand standard formulas like Newton's Second Law (F=ma), Ohm's Law (V=IR), or kinetic energy (E_k = \frac{1}{2}mv^2).

2. Focus on High-Frequency Topics

In Physics, prioritize Optics, Units, and Simple Machines. In Chemistry, memorize common names of chemical compounds, pH scale values, and basic periodic table trends. In Biology, memorize human organ systems, disease vectors, and vitamin classifications.

3. Analyze Previous Years' Questions (PYQs)

Solving past 5-10 years' questions reveals repeating patterns. SSC often repeats basic questions on human anatomy, SI units, and common acid-base reactions. To analyze these patterns interactively, you can access previous year question papers for SSC on ExamBhai and solve topic-wise quizzes.

4. Create Revision Flashcards

Prepare short notes or digital flashcards for quick revision. Memorize scientific names of plants and animals, discovery dates of key inventions, and core physical constants. Consistent revision keeps factual details fresh in your memory.

5. Take Regular Timed Mock Tests

Since General Awareness questions require fast retrieval, aim to complete the entire 25-question section within 6 to 8 minutes during your test series. You can take live topic tests for SSC on ExamBhai to boost your confidence and track your speed.

Cut-Off Trends

Understanding historical cutoff trends provides a clear benchmark for target scores. Cut-offs vary every year depending on candidate volume, exam difficulty, and total vacancies.
