The BLNST is not hard — yet candidates still slip
The full legal text is long; details fade even after reading it end to end
Look-alike wording such as “appoint” vs “approve” is easy to mix up
No idea which chapter is your weakest, so revision lacks direction
Realising the test is still outstanding right before an application deadline
133,297 real answers show why the BLNST trips people up
Every figure below comes from real attempts logged in the 10min BLNST question bank — not marketing claims, but how candidates actually perform.
The two areas are nearly identical
The questions candidates fail most (real correct rate)
“For a case taken over by the Office for Safeguarding National Security, who reports it to the central authorities for approval?” Over 2,400 candidates picked “the HK National Security Committee,” but the answer is “the HKSAR Government or the Office” — a one-word difference.
Data as of July 2026, covering cumulative attempts across the full bank, not unique candidates; the correct rate updates as more answers come in.
