Every chapter in Class 11 Accountancy is a different application of one equation: Assets = Liabilities + Capital. Journal entries maintain this equation. Ledger accounts organise it. The Trial Balance verifies it. The Balance Sheet presents it. Students who see this thread find each chapter logical and connected. Students who don't see it treat each chapter as a separate set of rules to memorise — and eventually, under exam pressure, the rules blur together and marks are lost.
Class 11 Accountancy is also the foundation for Class 12 Partnership and Company Accounts. A student who doesn't own journal entries, ledger posting, and trial balance preparation in Class 11 will spend twice as long on Class 12 topics — and still feel shaky. The reference sheet at the end of this guide gives you every golden rule, every key journal entry format, every depreciation formula, and the standard format for Trading, P&L, and Balance Sheet. Build these foundations now.
Where the Marks Come From in Class 11 Accountancy
Class 11 Accountancy theory carries 80 marks. Part A — Financial Accounting I covers Basic Accounting Terms, Theory Base, Recording Transactions, Ledger, Special Purpose Books, and Bank Reconciliation Statement. Part B — Financial Accounting II covers Depreciation, Provisions and Reserves, Bills of Exchange, Financial Statements, and Accounts from Incomplete Records. Internal Assessment: 20 marks (practical work, project, viva).
Part B (Recording Transactions, Trial Balance, Subsidiary Books, Bills, BRS) is the highest priority — approximately 50% of preparation time recommended here.
The Accounting Equation Is Not a Chapter. It Is the Thread That Connects Everything.
Assets = Liabilities + Capital
Every transaction in Accountancy is a rearrangement of this equation. A journal entry is a record of this rearrangement. A ledger is a collection of these rearrangements by account. A Trial Balance verifies the equation holds. A Balance Sheet presents the equation at a point in time. Students who see this thread in every chapter never get confused about which account to debit or credit.
The specific dependency that most students discover too late: you cannot prepare final accounts without a correct Trial Balance, and you cannot prepare a correct Trial Balance without correct ledger postings, and you cannot post correctly to the ledger without understanding the golden rules for journal entries. Rushing through journal entries and ledger in the first month of school means every subsequent chapter is built on a shaky foundation. Own the golden rules first — the rest follows.
The Three Golden Rules — The Only Framework You Need for Every Journal Entry
Every journal entry in Accountancy is determined by three golden rules. Before writing any entry, identify what type of account each affected account is — Personal, Real, or Nominal. Then apply the corresponding rule. This is the complete decision framework for every debit and credit in Class 11 and Class 12.

Bank Reconciliation Statement — The Most Common Error Source in Class 11 Accountancy
The Bank Reconciliation Statement (BRS) is a statement that reconciles the difference between the Cash Book balance and the Passbook (bank statement) balance on a given date. It carries approximately 7 marks and has one of the highest error rates in Class 11 Accountancy — not because the concept is hard, but because students confuse the direction of adjustment consistently.
The framework that prevents all errors: Always start from the Cash Book balance. Add or subtract items that explain the difference between Cash Book and Passbook.
Items that appear in Passbook but not in Cash Book (yet)
Interest credited by bank (not yet entered in Cash Book) → Add to Cash Book balance. Bank charges debited by bank (not yet entered in Cash Book) → Subtract from Cash Book balance. Direct deposits by customers → Add. Direct payments by bank (standing orders) → Subtract.
Items that appear in Cash Book but not in Passbook (yet)
Cheques issued but not yet presented for payment → Add back to Cash Book balance (they reduce Cash Book but haven't reduced Passbook yet). Cheques deposited but not yet collected by bank → Subtract from Cash Book balance (they increase Cash Book but haven't increased Passbook yet).
Depreciation: Two Methods, Specific Journal Entries, and a Question That Appears Every Year
Depreciation carries approximately 10 marks in the annual exam and has two distinct methods — each with its own formula, journal entries, and asset account presentation. CBSE boards test both, either as separate calculations or as a comparison question.
Straight Line Method
Depreciation is calculated on the original cost every year — the same fixed amount is charged annually regardless of book value. Asset reaches exactly the scrap value at the end of useful life. Best when: asset is used uniformly across its life.
Rate % = (Annual Depreciation / Cost) × 100
Written Down Value Method
Depreciation is calculated on the book value (cost minus accumulated depreciation) each year — the amount decreases every year. Book value never reaches zero — there is always a residual. Best when: repairs and maintenance increase over time (higher depreciation early offsets lower repairs).
WDV = Cost × (1 − Rate%)^n after n years
Journal entries for depreciation (same for both methods):
At year end: Depreciation A/c Dr | To Asset A/c (or Provision for Depreciation A/c)
Transfer to P&L: P&L A/c Dr | To Depreciation A/c
When Provision for Depreciation A/c method is used (more common in board papers): Depreciation A/c Dr → To Provision for Depreciation A/c. The Asset A/c remains at cost. On disposal: Provision for Depreciation A/c Dr (accumulated depreciation) + Asset Disposal A/c Dr (sale proceeds) → To Asset A/c. Profit/Loss on disposal transferred to P&L.

Genelis is an AI-powered personalized learning platform built on Adaptive Personalized Intelligence. The Genelis learning system tracks your accuracy separately across all Class 11 Accountancy chapters — distinguishing golden rule errors from format errors, and BRS direction confusion from depreciation calculation mistakes. Every wrong answer is logged to your wrong-question notebook and directed for reattempt.

(Being goods sold for cash)
(Being goods sold on credit to [name])
(Being cash received from [debtor])

Adjusting Entries
(Being [expense] outstanding for the period) Outstanding expense = accrued expense = expense incurred but not yet paid. Shown as current liability in Balance Sheet.
(Being [expense] paid in advance) Prepaid expense = expense paid in advance. Shown as current asset in Balance Sheet.
(Being amount written off as bad debt) Bad debt = irrecoverable amount. Transferred to Debit side of P&L Account at year end.
(Being provision created for doubtful debts)
(Being goods withdrawn for personal use) Not Sales A/c — goods taken for personal use reduces purchases, not records a sale.

Depreciation
Rate % = [(Cost − Scrap Value) / (Cost × Useful Life)] × 100
Depreciation (Year 2) = (Cost − Year 1 Dep) × Rate%
Book Value = Cost × (1 − Rate/100)ⁿ after n years
Loss on sale = Book Value at date of sale − Sale Price (if +ve)
