ISSB preparation: frequently asked questions

ISSB is 100 MCQs in 120 minutes. There is no negative marking, so never leave a question unanswered. The subject weightage is listed in full on this page.
Who conducts the ISSB exam?
Inter Services Selection Board is conducted by Inter Services Selection Board. Always confirm dates, eligibility and the fee on the conducting body's own advertisement, since those change every cycle.
How should I prepare for ISSB?
Work through the syllabus one topic at a time, solving MCQs on each topic until you are consistently scoring above 80 percent, and read the explanation on every question you get wrong. Move to solved past papers once a subject feels solid, then sit full-length timed mocks in the final weeks so the clock stops being a surprise.
Are ISSB past papers available for free?
Yes, free and with no signup. ISSB past papers on TestUstad are solved online rather than downloaded as a PDF, so each paper is timed and marked automatically and every answer comes with an explanation. That is the difference between reading a paper and actually sitting it.
Is ISSB preparation on TestUstad really free?
Yes. Solving ISSB MCQs is free and unlimited: no daily limit, no trial that expires, no card, and no account needed to start. Paid plans only add the things that require your history to be saved, which is score tracking over time, weak-topic analytics and full-length premium mock tests.
