Guide overview
01
Format and Pass Mark
For degree and professional grades, BLNST is a 30-minute bilingual test with 20 multiple-choice questions. Candidates answering at least 10 out of 20 correctly are deemed to have a pass result acceptable for civil service recruitment.
02
Official Scope
The test covers the Basic Law and the National Security Law. Build your map around institutions and powers, rights and duties, external affairs, finance and economy, interpretation and amendment, annexes, and core national-security principles and offences.
03
Booking and Retake Risk
Digitalised BLNST generally runs at the Wanchai Recruitment Centre on working days, with six timeslots per day and a rolling eight-week booking window. Absence or failure may create a three-month suspension.
04
20-Question Practice Rhythm
Because the pass mark is 10 out of 20, do not aim for exactly 10. Train until you can consistently score above the pass line with time left.
05
Free Study Sequence
Start with the official scope, then complete a 20-question mixed set. Mark every miss by topic and re-read only the relevant official provision.
