NISM Series VI (Depository Operations) common mistakes
NISM Series VI (Depository Operations) · Understand the traps and how to avoid them.
Treating a Demat account as a single-owner product and answering questions about joint holdings, nomination, and 'either or survivor' / 'anyone or survivor' operating instructions as if they were identical across all holder combinations.
Candidates learn the basic account-opening flow first and then skim the joint-holder and nomination annexures, so they assume the operating instruction is a free choice for any joint account rather than something constrained by the holder combination and the nomination status.
What to do instead
Build a one-page matrix of joint-holder combinations versus permitted operating instructions and nomination rights, and re-derive it from the depository's stated rules rather than from memory. Test yourself by writing the matrix from blank paper until it is exact.
Confusing the roles of the depository, the Depository Participant (DP), and the issuer/RTA when asked who performs a given action, such as who opens the account, who credits securities on allotment, who freezes an account, or who maintains the beneficial owner record.
The three parties collaborate on almost every transaction, so candidates memorise the end-to-end flow as one undifferentiated process and lose track of the handoff points where responsibility actually changes.
What to do instead
For each of the ten or so core activities (account opening, dematerialisation, rematerialisation, allotment credit, transfer, pledge, freeze, transmission, corporate action credit, closure), write who initiates, who authorises, and who records. Learn the handoffs, not the story.
Answering dematerialisation questions by describing the investor's side only and omitting the DRF/DRN chain, the role of the RTA, and what happens when the request is rejected or the certificate is defective.
The investor-facing steps are intuitive and easy to recall, while the back-end reconciliation between the DP, the depository, and the issuer's registrar is abstract and gets skipped during revision.
What to do instead
Draw the dematerialisation request flow as a numbered sequence with the document or record that moves at each step (request form, request number, confirmation, credit). Then add a branch for rejection and for a discrepancy in the certificate details, and memorise both branches.
Mixing up the pledge and hypothecation flows, specifically who can invoke a pledge, whether the pledgee needs a demat account, what the 'reason' field is for, and how a pledge is closed versus invoked.
Both are security arrangements over demat holdings and share vocabulary, so candidates collapse them into one concept and then guess on the distinguishing questions.
What to do instead
Write a side-by-side comparison covering the parties, the accounts required, the initiating entity, the closure path, and the invocation path. Anchor it with one worked example each and check the exact terminology the depository uses for each step.
Applying the wrong transmission documentation set to the wrong situation, for example using the nomination route when no nomination exists, or treating a joint-holder survivor case as a legal-heir case.
Transmission sits at the intersection of account structure, nomination, and succession law, and candidates revise the document list without linking it to the triggering condition.
What to do instead
Rewrite transmission as a decision tree: first branch on nomination present or absent, second on joint or single holding, third on value/small-value thresholds if applicable. Attach the required documents to each leaf and practise classifying ten short scenarios into leaves.
Assuming corporate action benefits are credited on the same date and in the same manner for all action types, and ignoring the record date / ex-date distinction and the role of the depository versus the issuer.
Corporate actions are taught as a list of event types rather than as a timing and entitlement problem, so candidates memorise names but not the mechanics of entitlement determination.
What to do instead
For each action type (dividend, bonus, split, rights, merger, buyback), record who declares it, which date fixes entitlement, who computes the benefit, and how it reaches the demat account. Drill the record date versus ex-date question until it is automatic.
Answering freeze, lock-in, and 'stop transfer' style questions as though they were interchangeable restrictions, without stating who can impose each, who can remove it, and what the account holder can still do while it is in force.
All three restrict dealing in securities and are described with overlapping language, so the distinctions blur under exam pressure.
What to do instead
Make a restriction table with columns for who imposes, the grounds, the effect on debit and credit, and the removal authority. Include the case of a freeze imposed by a court or investigating agency versus one requested by the holder.
Calculating or quoting charges, fees, and penalties from vague recollection instead of knowing the structure and who sets each component.
Fee figures change and candidates try to memorise numbers rather than the framework, so they cannot reason when a specific figure is not recallable.
What to do instead
Learn the framework: which charges are set by the depository, which by the DP, which are statutory, and how they are disclosed to the client. Where a specific current figure is genuinely required, verify it from the current official schedule rather than trusting a remembered number.
Skipping the grievance redressal and compliance chapter because it feels administrative, then failing questions on the escalation ladder, the role of the depository's grievance cell, and the difference between a DP-level complaint and a depository-level complaint.
Candidates prioritise transaction mechanics and treat redressal as low-yield, but it is a compact, highly testable chapter with clear right answers.
What to do instead
Memorise the escalation ladder as an ordered list with the trigger for moving to the next level, and note the timelines attached to each stage. This chapter is small enough to secure fully; treat it as guaranteed marks.
Revising only from short summaries and never practising scenario-style questions that require applying a rule to a described situation, so recall is strong but application fails.
The exam tests judgement in realistic situations, and passive reading creates a false sense of mastery because recognition feels like knowledge.
What to do instead
Convert every rule you revise into a two-line scenario and answer it aloud before checking. Track errors by domain rather than by question, and re-test only the domains where your error rate stays above your target.
