SSC CHSL or SSC CGL: differences and how to choose

A student who has just finished Class 12 can take SSC CHSL but not SSC CGL. A graduate can take both. So the question "CHSL or CGL?" mostly comes from graduates, and for most of them the honest answer is that it doesn't have to be one or the other. The two exams overlap so heavily that preparing well for one takes you most of the way to the other. What matters is understanding the few places where they differ, so you don't get caught out by them.

Side by side

Both tiers share the same basic mechanics: 2 marks and −0.50 per question in Tier 1, 3 marks and −1 in Tier 2, 15-minute sectional timers in Tier 1. Maths and reasoning in Tier 2 are 30 questions each in both exams.

Where the marks differ

The Tier 2 tables look similar, but CGL gives English and GA more weight.

So a candidate whose English is strong gains a little more in CGL. A candidate whose GA is weak loses a little less in CHSL. Otherwise, your preparation for Tier 2 maths and reasoning is identical.

Level of difficulty

• CHSL questions are generally more direct. A percentage question may take two steps rather than four.
• CGL Tier 2 maths goes further into advanced algebra, geometry and trigonometry, and CGL English uses harder vocabulary and longer passages.
• Cut-offs follow competition and vacancies, not the level of the paper. An easier paper often means a higher cut-off, so neither exam is "easy".

An example of the gap. A CHSL-style question: If x + 1/x = 4, find x² + 1/x². Square both sides: x² + 2 + 1/x² = 16, so x² + 1/x² = 14. A CGL-style question might ask for x³ + 1/x³ instead: (x + 1/x)³ − 3(x + 1/x) = 64 − 12 = 52. Same idea, one step further. That is the typical difference.

Posts and careers

• CGL posts start at higher pay levels and several carry supervisory or field responsibilities, such as inspectors in tax departments.
• CHSL posts are entry-level clerical and data roles, with growth through seniority and departmental exams.
• Many people join through CHSL and later clear CGL while working. The skills you use daily in a clerical job, like reading rules carefully and writing clean notes, also help in the CGL English section.

Should a graduate take both?

For most graduates, yes, for three reasons:

1. The syllabus overlaps almost completely. The extra CGL content is a thin layer on top.
2. Two exams mean two chances in a year, on different dates.
3. A CHSL post gives income and stability while you aim for CGL.

The one real addition for CHSL is the typing test for LDC/JSA. It is a physical skill that takes weeks to build, and CGL doesn't prepare you for it. If you plan to take both, start typing practice early.

A combined plan

A simple rule is to prepare at CGL depth and practise at CHSL speed. Study the harder algebra and geometry because CGL needs them. Then take CHSL mocks to train yourself to finish direct questions fast.

If you are in Class 12 or college

• Take CHSL as soon as you are eligible. It gives real exam experience and a real chance of selection.
• Don't drop your degree for it. CGL opens after graduation, and a degree keeps state exams and banking open too.
• Our guide to preparing for CHSL straight after Class 12 covers balancing college with preparation.

Practice

1. What is the minimum qualification for CGL?
2. How many scored marks does CHSL Tier 2 carry, and how many does CGL Tier 2 Paper I carry?
3. Which exam has a typing test for clerical posts?
4. If x + 1/x = 5, find x² + 1/x².
5. Why might a graduate take CHSL even if CGL is the goal?

Answers:

1. Graduation.
2. CHSL 360; CGL Paper I 390.
3. SSC CHSL, for LDC/JSA.
4. 5² − 2 = 25 − 2 = 23.
5. The syllabus overlaps, it gives a second chance each year, and a CHSL job provides income and stability while preparing for CGL.

What to do next

• Check your eligibility for both exams, including the age limit for the CGL posts you want.
• Mark both exam windows on one calendar.
• Prepare maths at CGL depth, but take CHSL mocks for speed.
• Start typing practice now if you want LDC/JSA posts.
