TSSPDCL Sub-Engineer

It is a single objective paper of multiple-choice questions covering the technical and non-technical syllabus, followed by certificate verification for shortlisted candidates. The official notification sets the number of questions, marks per question, negative marking if any, and the qualifying marks, so read the current notification on the TSSPDCL website before you plan your attempt.

Most questions are diploma-level and direct, with a few numericals that need two or three steps. The difficulty comes from breadth and time pressure rather than depth. Candidates who are strong in power systems but weak in aptitude, English or digital electronics typically find the paper harder than expected.

Yes, you may apply again whenever TSSPDCL issues a fresh notification, provided you still meet the age and qualification conditions. There is no limit on attempts as such, but the eligibility cut-off date and age relaxation rules change between notifications, so verify them each time on the official site.

The duration is fixed by the notification and is stated on the hall ticket. Practise with a watch: aim to clear the aptitude, reasoning and English block quickly so the technical numericals get the remaining time. Do not let a single lengthy calculation consume more than about two minutes; mark it and return later.

Start with circuit theory, because machines, power systems and power electronics all depend on it. Then take machines and power systems together, since transformer and feeder problems overlap. Add measurements, power electronics and utilisation next, then electronics, safety and estimation. Keep aptitude, reasoning and English as a daily short session instead of a last-week cram.

Three mistakes recur: ignoring non-technical sections worth a tenth of the paper, memorising formulae without practising numericals, and skipping distribution-specific topics such as feeder voltage drop, earthing, metering and protective relays. Poor time allocation in the exam hall and careless unit conversion, especially in per-unit and transformer problems, also cost easy marks.

Whether negative marking applies is decided in the official notification for that recruitment year, so check it rather than assuming. If it applies, answer only when you can eliminate at least two options; blind guessing across many questions can erase the benefit of the questions you actually know.

Use them as diagnostics, not as a question bank to memorise. After each mock, list every wrong answer by topic and re-study that topic before the next test. Two or three timed mocks in the final month, with a full review afterwards, are worth more than ten mocks taken without analysis.

Yes, the syllabus includes English language and computer awareness. Expect grammar, vocabulary, comprehension, and basic computer terms such as hardware, operating systems, networking and internet use. These are scoring sections for candidates who prepare them, and they are commonly left unprepared by electrical candidates.
