SSC CGL Tier 2 Paper I strategy

Two candidates finish SSC CGL Tier 2 Paper I. The first attempts 125 of the 130 scored questions and gets 100 right: 100 × 3 = 300, minus 25 for wrong answers — 275 marks. The second attempts 110 and gets 104 right: 312 minus 6 — 306 marks. The second candidate answered fewer questions and still scored 31 marks more, a difference that can mean hundreds of ranks. That is the central lesson of Tier 2: with +3 for a right answer and −1 for a wrong one, accuracy is worth more than volume.

The structure again

Understanding negative marking

With +3 and −1, a wrong answer cancels a third of a right answer. The maths of guessing:

• If you can eliminate nothing, a random guess on four options has an expected value of (1/4 × 3) − (3/4 × 1) = 0 — no gain, only risk.
• If you can eliminate two options, a guess between the remaining two has an expected value of (1/2 × 3) − (1/2 × 1) = +1.

So: never guess blindly, but an informed guess with two options eliminated is worth taking.

Where rank is made

Module strategies

Mathematical Abilities

• Questions are harder and longer than Tier 1 — more algebra, geometry and trigonometry.
• Accuracy target: 90%+ on attempted questions.
• Do not attempt a question unless you are confident of the method.

Reasoning

• Similar types to Tier 1, sometimes more complex.
• Aim for near-complete attempts with high accuracy.

English

• 45 questions — including comprehension passages, cloze tests, error spotting, sentence improvement, vocabulary.
• Time management matters: vocabulary first, then grammar, then passages — or passages first if you are a fast reader. Decide in mocks.
• Read the whole sentence before choosing an error.

General Awareness

• 25 questions: answer what you know; skip what you don't.
• Revise static GK and science heavily between tiers.

Section III and IV: the qualifying hurdles

• Computer Knowledge Test — 20 questions on basics, MS Office, internet and security. Qualifying, but a failure eliminates you. Two to three weeks of focused revision is usually enough.
• Data Entry Speed Test — typing a passage on the computer to a required speed. Practise typing daily if you are not already comfortable (see our post on DEST).

Using the gap between tiers

The gap between Tier 1 and Tier 2 is usually a few weeks to a couple of months.

Don't wait for the Tier 1 result to start. If you think you have cleared, begin Tier 2 preparation immediately.

Mock tests

• Take Tier 2-level mocks, not Tier 1 mocks — the difficulty is different.
• After each mock, record wrong answers by type: careless errors, concept gaps, and guesses. Eliminate careless errors first — they are the cheapest marks to recover.

Practice

1. Calculate the score of a candidate who attempts 130 questions with 118 correct.
2. Why is a blind guess in Tier 2 worth nothing on average?
3. Which module carries the most marks?
4. Which Tier 2 sections are qualifying only?
5. Plan your next four weeks using the table above.
