All 10 Computer Science & IT subjects. Complete notes for fast revision plus exam-level tests for Paper 1 (Part C) and Paper 2. Built by Piyush Wairale, IIT Madras.
SSC JE 2026 Paper 1 is a 200-mark CBT held from 2 to 6 November 2026, and half of it (100 marks, Part C) is Computer Science & IT. The fastest way to score is to revise all 10 CS & IT subjects from concise notes, practise subject-wise tests to close gaps, and then attempt full-length mocks under the real 2-hour, 0.25 negative-marking pattern. The SSC JE 2026 Test Series & Notes (CS & IT) by Piyush Wairale packs all of this into one course for ₹199.

Get the CS & IT Test Series for ₹199| Part | Questions | Marks |
|---|---|---|
| Part A: General Intelligence & Reasoning | 50 | 50 |
| Part B: General Awareness | 50 | 50 |
| Part C: Computer Science & IT | 100 | 100 |
| Total | 200 | 200 |
Negative marking: 0.25 mark per wrong answer. Paper 1 is qualifying (minimum 30% for UR, 25% for OBC/EWS, 20% for others) and shortlists candidates for Paper 2.
| Subject | Questions | Marks |
|---|---|---|
| Part C: Computer Science & IT | 100 | 300 |
Negative marking: 1 mark per wrong answer. Same Computer Science & IT syllabus as Paper 1 Part C, but deeper and costlier mistakes. Paper 2 marks decide the final merit list, which is exactly why timed practice matters.

Paper 1 starts on 2 November 2026. Here is how to use the notes and tests in the time left.
Tip: With 0.25 negative marking in Paper 1, a wrong answer costs only a quarter of a right one, so an educated guess after eliminating even one option is worth taking. In Paper 2 (1 mark lost per wrong answer, 3 marks per right one) guess only when you can eliminate at least two options. Mocks are where you learn your safe-guess threshold.
Piyush Wairale is the Founder & CEO of PiyushAI Edtech and holds an M.Tech in Ocean Engineering from IIT Madras, where he also served as an instructor in the IIT Madras BS Degree Programme. His engineering background and years of exam teaching shape every set of notes and tests.
As per the SSC notice dated 1 October 2026, Paper 1 (CBT) is scheduled from 2 to 6 November 2026. Paper 2 is tentatively scheduled for December 2026. Always confirm on ssc.gov.in.
Paper 1 is a 2-hour CBT of 200 questions for 200 marks: Reasoning (50), General Awareness (50) and Part C Computer Science & IT (100), with 0.25 negative marking. Paper 2 is a 2-hour CBT of 100 Computer Science & IT questions for 300 marks, with 1 mark deducted per wrong answer. Paper 1 is qualifying; the final merit list is based on Paper 2.
Engineering Mathematics, Digital Logic, Computer Organization and Architecture, Programming and Data Structures, Algorithms, Theory of Computation, Compiler Design, Operating Systems, Databases (DBMS) and Computer Networks.
Pick one that covers all 10 CS & IT subjects, follows the current Paper 1 and Paper 2 pattern and includes notes for quick revision. The SSC JE 2026 Test Series & Notes (CS & IT) by Piyush Wairale offers exactly this for ₹199.

Yes. Paper 1 Part C and Paper 2 test the same Computer Science & IT syllabus, so the same notes and practice prepare you for both. Paper 2 goes deeper and carries heavier negative marking.
If you have studied Computer Science & IT before, two focused weeks are enough to revise high-yield topics, take full-length mocks and fix weak areas. Prioritise Part C, revise formulas daily and analyse every mock.
Candidates with a Bachelor's degree in Science with Physics, or in Computer Science, IT, Electronics or Telecommunication related disciplines, subject to the exact qualification and age limits (calculated as on 1 August 2026) in the official notification.
Scientific Assistant (IMD) and JE posts are in Pay Level 6 (7th CPC): ₹35,400 to ₹1,12,400 plus applicable allowances.
