Official CSI resources for BCO: course page, curriculum, exam credits, and current structure checks for the 80-question and legacy 90-question versions.
On this page
Use these CSI sources when you want the official BCO scope and current structure notes rather than recycled supervision summaries. That matters because BCO has both a current 80-question structure and a legacy 90-question path for earlier enrollees.
BCO sits in the branch-control and suitability-supervision lane. That means the official source set is most useful when you need to confirm whether you are in the branch-supervision lane at all and whether the current or legacy exam structure applies to you.
it tells you whether you are training for the current or legacy structure and where the weight sits
move to the curriculum page
it gives the chapter order once the structure is clear
use the course page last
it is the operational source for enrollment and course context rather than the main weighting source
then move into exact web practice
that is the right stage to train speed on the structure that applies to you
Common weak resource habits
treating BCO as broad ethics theory instead of a branch-control exam
ignoring the legacy 90-question note when you enrolled earlier
memorizing suitability rules without tying them to evidence quality and supervision
reviewing complaints, account opening, and branch controls as separate silos instead of one workflow
Strongest use of the official source set

exact web practice
train control-flow and evidence judgment after the branch-supervision frame is already clear
How to use these BCO resources
Use the curriculum to build your reading order and the exam-credits page to decide where review time matters most.
Treat the course page as the administrative source and the curriculum plus exam-credits pages as the content-planning sources.
Reconfirm the official CSI pages before exam week if your notes come from an older cycle or if you enrolled before July 5, 2023.
If your real need is representative-facing conduct review rather than branch supervision, compare with CPH.
If your real question is BCO or IDSC?, answer that on the course page first and then use the curriculum plus exam-credits pages to confirm whether you are in the branch-control lane or the broader supervisor lane.
