Which subject should I start with?

Your weakest, because a weak subject takes the longest to organise. The strong ones can be sharpened quickly later.

How many marks does each subject carry?

The split is stated in the commission’s circular and can change by decision. The structure is explained at /bcs/mark-distribution; confirm the figures at bpsc.gov.bd.

Should every subject get equal time?

No. Give more to the large, fact-dense subjects and settle the small ones quickly — time should follow question density.

BCS Subject-wise Preparation

Treating the preliminary as one exam makes preparation shapeless. It is in fact ten separate subjects, and each has its own character — some are rules, some are facts, some are pure drilling.

This section keeps a page per subject: what to read, from which source, in what order, and where candidates repeatedly stumble.
