About this exam

The General Science & Technology paper is one of the subject papers in the BCS Written Examination, the second stage of Bangladesh's Civil Service examination after the preliminary screening test. Candidates who clear the preliminary stage sit a series of descriptive papers, and this one tests whether a future civil servant can explain scientific ideas clearly, accurately and in organised prose. It is intended for generalist candidates rather than science specialists, so the emphasis falls on sound fundamentals and sensible application rather than on advanced mathematics. The syllabus spans five broad areas: basic physics and chemistry; biology, life sciences and public health; information technology and computer fundamentals; applied science, engineering and emerging technologies; and the scientific method, environment and science policy. Answers are handwritten in an answer booklet, so structure, diagrams, definitions and worked reasoning matter as much as the final fact. Strong preparation combines a standard school-level science foundation with regular reading of science coverage in national newspapers and popular science magazines, especially on technology, climate and public health. Practise writing timed answers on single topics, keep a one-page summary sheet per domain, and rehearse labelled diagrams from memory. Always confirm the current syllabus, marks distribution and examination schedule on the official BCS website, since these are set by the commissioning body and change between cycles.

What you'll study

Common questions

About BCS Written General Science & Tech preparation

What is the format of the General Science & Technology paper?

It is a descriptive, essay-type paper written in an answer booklet during the BCS Written Examination. You compose full written answers rather than shading multiple-choice options. Questions typically ask you to define, explain, compare or apply a concept, sometimes with a diagram. The official body publishes the current syllabus, marks distribution and paper structure on its website.

How difficult is this paper for a non-science graduate?

It is manageable. The paper rewards clear explanation of school-level science rather than specialist depth, and arts or commerce graduates routinely do well by rebuilding fundamentals systematically. The real difficulty is recall under time pressure and writing organised answers, not the conceptual ceiling. Budget more time for physics and chemistry if your background is elsewhere.

How much time do I get, and how many questions are there?

Question counts, marks and time limits are fixed by the official examining body for each cycle and are published on its website and in the official advertisement. Do not rely on numbers from coaching notes or previous years, since these change. Check the current circular before you plan your answer-per-question timing.

Can I retake the written examination if I fail?

Retake rules are set by the official commission and can change between cycles, so confirm the current policy on its website. In practice, candidates who are not successful typically must wait for a future circular and re-enter the process from the stage the rules require. Eligibility also depends on age and attempt limits.

In what order should I study the five domains?

Start with physics and chemistry fundamentals, because they underpin the applied and emerging technology section. Then take biology and public health, followed by information technology. Finish with applied science and science policy, which draw on the earlier domains. Interleave revision rather than studying one domain to exhaustion before moving on.

What are the most common ways candidates lose marks?

Answering the question that was not asked, writing long unstructured paragraphs, omitting units and definitions, and skipping diagrams where a labelled sketch would earn marks. Poor time allocation is another frequent problem: candidates over-write the first answer and rush the last. Practise timed writing so you learn to stop and move on.

Do I need to memorise equations and constants?

Learn the small set of core equations and constants that explain everyday phenomena, and be able to state what each symbol means and its unit. Examiners reward correct reasoning and dimensional sense more than long derivations. Keep a single revision sheet of formulas with units and practise applying them to simple numerical examples.

How current should my technology and science-policy knowledge be?

Reasonably current. Questions on emerging technologies, climate, renewable energy and public health often expect awareness of recent developments and national policy context. Read science coverage in reputable newspapers and official policy documents regularly, and note concrete Bangladeshi examples, which make answers more convincing than generic global statements.

How do I practise for a descriptive science paper?

Write full answers by hand under timed conditions, then mark them against the syllabus wording. Keep a one-page summary per domain and redraw key diagrams from memory weekly. Explaining a concept aloud to someone else exposes gaps quickly. Past paper questions are useful for practice, but verify the current syllabus before assuming topic coverage.
