Alerts and Updates for DSSSB PGT Computer Science

One caution specific to this subject. Some coaching pages describe the Computer Science paper as 200 questions in two hours, which is the Section B block quoted on its own. The scheme of examination for DSSSB PGT posts is a single three-hour computer-based test of 300 questions and 300 marks, of which the subject section is 200. Plan the sitting for three hours, not two.

The application window, fee and exam-schedule notice are common to every subject paper within a given DSSSB PGT advertisement. Computer Science is the exception in this family: Post Code 15/24 sits in the earlier NDMC advertisement rather than in the combined 824/24 to 834/24 block, so it ran on its own date, 22 September 2025, and finished its e-dossier stage before most other PGT subjects had sat their papers.

The single most common error here is searching for the wrong thing. There is no DSSSB post called PGT Computer Science in the main combined advertisement. The live post is Post Code 15/24, PGT (Informatics Practices or Computer Science) in NDMC, from Advertisement 05/2024, and every notice, key and result for it is filed under that post code. Candidates who track the 824/24 to 834/24 series miss their own result notice entirely.

DSSSB identifies candidates by post code, and this subject's post code, 15/24, does not look like the others in the PGT family, which run 824/24 to 834/24 for the combined 2024 advertisement or 03/25 to 10/25 for the 2025 one. The NDMC Informatics Practices post is advertised under the 05/2024 advertisement, numbered F.1(255)/P&P-I/DSSSB/2024/Advt./5253 and dated 5 March 2024. DSSSB also publishes its indicative syllabus as a separate page titled for Post Code 15-24. The practical consequence is that the exam calendar, admit card release and result notice for Computer Science are decoupled from the rest of the PGT recruitment. When checking the DSSSB results page, search the post code string, not the subject.

Reported figures for 15/24 put the vacancy at three unreserved NDMC posts, with 342 candidates appearing at the 22 September 2025 test and 10 called for e-dossier under Notice No. 315 dated 16 February 2026, at a minimum of 160.50 out of 300. Two inferences follow. First, DSSSB calls roughly three candidates per vacancy to the dossier stage, so being shortlisted is not selection. Second, 160.50 is about 53.5 per cent, well above the 40 per cent unreserved qualifying floor but far below the near-perfect marks seen in high-density subjects. A small applicant pool, not an easy paper, is the usual explanation, and a candidate targeting this post should aim for the high 170s rather than the shortlist line.

Computer Science departs from the science and humanities pattern of requiring a Master's in the concerned subject. The reported essential qualification accepts a B.E. or B.Tech in Computer Science or Information Technology, an M.Sc. in Computer Science or IT, or an MCA, from a recognised university. The B.Ed. or equivalent NCTE-recognised training requirement that applies to all PGT posts still applies, and that is where engineering graduates most often fall out: a strong B.Tech with no B.Ed. is not eligible. The reported upper age limit for unreserved candidates is 36 years with the standard category relaxations. Verify the exact qualification clause in the advertisement text, because NDMC posts sometimes phrase the clause differently from the Directorate of Education posts.

Reported Section B coverage spans computer aptitude and number systems, hardware and software concepts including RAM and ROM distinctions, computer networks with bus, star, ring and mesh topologies, LAN and WAN, switches, routers, wireless security and ARPANET history, digital electronics with Boolean algebra, logic gates, Karnaugh map simplification, adders, subtractors and flip-flops, operating systems including MS-DOS, Windows and Linux variants, programming and object-oriented design across C, C++, JavaScript, PHP and UML, databases and web development with SQL Server, Oracle PL/SQL, JSON and the .NET, ASP.NET and ADO.NET stack, and distributed and grid computing. The breadth is the difficulty. A recent MCA graduate strong in one modern stack will still lose marks on digital electronics and on the older Microsoft web technologies, which remain examinable.

Reported 2022-cycle DSSSB PGT Computer Science cut-offs were, for the male papers, 176.19 UR, 142.88 OBC, 145.68 SC and 102.71 ST, and for the female papers 185.59 UR, 155.08 OBC and 99.41 ST, out of 300. In the same reported set Commerce male UR stood at 148.96 and Economics male UR at 175.51, so Computer Science was at or near the top of the family. Against that history, the 160.50 e-dossier mark for 15/24 looks like the effect of a 342-candidate field rather than a change in standard. Prepare to the historic band. The gap between the two numbers, roughly 16 to 25 marks, is about the size of the digital electronics and networking blocks, which is where a broad preparation pays.
