Paper-II carries 50 of the 600 marks in IP LDCE — the smallest paper, and the one with the best return on an evening of work. Papers I and III are 275 multiple-choice questions between them; you cannot learn those in a night. Paper-II is three answers with three fixed structures, and it has its own qualifying floor: 40% for General candidates, 33% for SC/ST/PwBD. Scoring well in the objective papers does not rescue a Paper-II below the floor.

One hour for all three. That is roughly 15 minutes for the note, 15 for the draft, and 25–30 for the charge sheet, which is the longest to write and the easiest to score because its shape is prescribed.

A note is not an essay and not an opinion piece. It is a structured summary of a case ending in a specific recommendation that an officer can approve or reject. The Manual of Office Procedure conventions are what is being marked: brevity, references to the rule or precedent relied on, and a clear point for decision.

<div style="background:#0f1420;color:#e8ecf3;border:1px solid #223049;border-radius:12px;padding:18px 20px;margin:18px 0"><h3 style="margin:0 0 10px;font-size:17px;font-weight:700;color:#fff">The five parts of a note, in order</h3><ul style="margin:0;padding-left:20px"><li style="margin:6px 0;line-height:1.6"><strong>The facts</strong> — what happened, dated, in the order it happened. No adjectives.</li><li style="margin:6px 0;line-height:1.6"><strong>The reference</strong> — the rule, order or precedent that governs it, cited by number.</li><li style="margin:6px 0;line-height:1.6"><strong>The issue</strong> — the point on which a decision is needed, stated as one sentence.</li><li style="margin:6px 0;line-height:1.6"><strong>The analysis</strong> — the options, and why one is to be preferred. Two short paragraphs.</li><li style="margin:6px 0;line-height:1.6"><strong>The recommendation</strong> — "It is submitted for approval that …" with the exact action sought, and the level competent to approve it.</li></ul><p style="margin:12px 0 0;font-size:13px;color:#93a4bf">Mark-losers: writing in the first person, arguing rather than submitting, and ending without naming the action sought.</p></div>

Drafting is the communication that goes out once the note is approved. The marks are in choosing the right form and getting its furniture right, not in the prose. Read the question for who is writing to whom: a letter to a member of the public is not an office memorandum to a subordinate office.

<div style="background:#0f1420;color:#e8ecf3;border:1px solid #223049;border-radius:12px;padding:18px 20px;margin:18px 0"><h3 style="margin:0 0 10px;font-size:17px;font-weight:700;color:#fff">The furniture the examiner looks for</h3><ul style="margin:0;padding-left:20px"><li style="margin:6px 0;line-height:1.6">File / letter number and the date</li><li style="margin:6px 0;line-height:1.6">The issuing office, and the addressee by designation — not by name</li><li style="margin:6px 0;line-height:1.6">A <strong>Subject:</strong> line that says what the letter is about in one line</li><li style="margin:6px 0;line-height:1.6">A <strong>Reference:</strong> line to the communication being replied to, with its number and date</li><li style="margin:6px 0;line-height:1.6">The body: the decision, the reason, the action required, and the date by which</li><li style="margin:6px 0;line-height:1.6">The closing, the signature block with designation, and <strong>Enclosures:</strong> if any</li><li style="margin:6px 0;line-height:1.6">Copy-to list, where the question implies other offices must know</li></ul></div>

This is a memorandum under Rule 14 of the CCS (Classification, Control and Appeal) Rules, 1965, and it is the largest single component of Paper-II. A charge sheet for a major penalty is not a letter asking for an explanation — that is the minor-penalty route under Rule 16. Under Rule 14 the disciplinary authority frames definite charges and puts them to the official with four annexures.

<div style="background:#0f1420;color:#e8ecf3;border:1px solid #223049;border-radius:12px;padding:18px 20px;margin:18px 0"><h3 style="margin:0 0 10px;font-size:17px;font-weight:700;color:#fff">The Rule 14 skeleton — write these headings out</h3><ul style="margin:0;padding-left:20px"><li style="margin:6px 0;line-height:1.6"><strong>Memorandum</strong> — naming the official and stating that it is proposed to hold an inquiry against him under Rule 14 of the CCS (CCA) Rules, 1965</li><li style="margin:6px 0;line-height:1.6"><strong>Annexure I — Statement of Articles of Charge</strong>: Article I, Article II … each one charge, stated as a definite allegation of misconduct</li><li style="margin:6px 0;line-height:1.6"><strong>Annexure II — Statement of Imputations of Misconduct or Misbehaviour</strong>: the facts, dates and amounts on which each Article rests</li><li style="margin:6px 0;line-height:1.6"><strong>Annexure III — List of documents</strong> by which the Articles of Charge are proposed to be sustained</li><li style="margin:6px 0;line-height:1.6"><strong>Annexure IV — List of witnesses</strong> by whom the Articles of Charge are proposed to be sustained</li><li style="margin:6px 0;line-height:1.6">The direction to submit a written statement of defence within 10 days (or the period the question specifies), and to state whether he desires to be heard in person</li><li style="margin:6px 0;line-height:1.6">The signature block of the disciplinary authority</li></ul><p style="margin:12px 0 0;font-size:13px;color:#93a4bf">Mark-losers, in order of frequency: merging the Articles of Charge with the Imputations into one list; omitting the two lists; forgetting the written-statement direction; and writing an explanation-seeking letter instead of a memorandum.</p></div>

<div style="background:#0f1420;color:#e8ecf3;border:1px solid #223049;border-radius:12px;padding:18px 20px;margin:18px 0"><h3 style="margin:0 0 10px;font-size:17px;font-weight:700;color:#fff">Getting the Articles of Charge right</h3><ul style="margin:0;padding-left:20px"><li style="margin:6px 0;line-height:1.6">One Article per distinct act of misconduct. Two acts in one Article is a drafting fault.</li><li style="margin:6px 0;line-height:1.6">Each Article names the conduct rule contravened — most often Rule 3(1)(i), (ii) or (iii) of the CCS (Conduct) Rules, 1964: absolute integrity, devotion to duty, and nothing unbecoming of a Government servant.</li><li style="margin:6px 0;line-height:1.6">State facts, not conclusions: "failed to remit ₹X collected on 12.03.2026", not "acted dishonestly".</li><li style="margin:6px 0;line-height:1.6">The Imputations then give the same facts with the detail — dates, amounts, documents — that the Articles only assert.</li></ul></div>

The constitutional backing for all of this is Article 311, which is also a named item in Paper-III: no civil servant may be dismissed, removed or reduced in rank except after an inquiry in which he has been informed of the charges and given a reasonable opportunity of being heard. Rule 14 is that inquiry.

Rule 11 of the CCS (CCA) Rules, 1965 lists them in one place, and a Paper-III question on which penalty is minor and which is major is close to free marks:

Two provisos worth carrying into the hall. Where the charge of assets disproportionate to known sources of income, or of accepting gratification other than legal remuneration, is established, the penalty imposed shall be removal or dismissal. And in an exceptional case, for special reasons recorded in writing, any other penalty may be imposed.

Rule 14 is the procedure for the major penalties; Rule 16 is the procedure for the minor ones; Rule 19 is the special procedure in certain cases; Rule 29 is revision and Rule 29-A is review, which is vested in the President alone.
