Accountancy is one of the highest-scoring subjects in Class 12 Commerce – yet it’s also the subject where students lose marks most silently. Not because they don’t know the syllabus, but because of small, repeated mistakes that add up in the board exam.
Here’s a clear breakdown of the top 15 mistakes Class 12 students make in Accountancy, along with practical ways to avoid them.
1. Skipping the Working Notes
Even when the final answer is correct, missing or unclear working notes can cost marks.
How to avoid it:
Always show calculations clearly with proper language support, even for simple adjustments. Examiners award step-wise marks.
2. Ignoring the Question Requirement
Students often solve the entire question correctly but answer more (or less) than what is asked.
How to avoid it:
Underline keywords like “calculate goodwill,” “prepare balance sheet,” “show necessary workings” before starting carefully read the actual requirement of the Question.

3. Incorrect Treatment of Adjustments
Common errors include:
• Wrong adjustment of outstanding and prepaid expenses
• Missing accrued income and unearned income
• Double-counting depreciation
How to avoid it:
Practice adjustments separately and revise them daily during the final weeks.
4. Poor Presentation of Accounts
Messy formats, unclear headings, or misaligned figures make it hard for examiners to award marks.
How to avoid it:
Maintain proper formats, clear headings, writing narrations with all journal entries and neat columns. Presentation matters in Accountancy.
5. Mixing Up Similar Concepts
Examples:
• Capital Reserve vs General Reserve
• Profit on Revaluation vs Revaluation Reserve
• Debit vs Credit nature of items
How to avoid it:
Maintain comparison Points while revising similar concepts.
6. Not Practising Enough Board-Level Questions
Studying theory without sufficient numerical practice leads to time pressure in exams.
How to avoid it:
Solve past board questions and sample papers under timed conditions.
7. Calculation Errors Due to Speed
Rushing leads to:
• Wrong totals
• Incorrect balancing
• Carry-forward mistakes
How to avoid it:
Balance speed with accuracy. Recheck totals before moving to the next question.
8. Leaving Questions Half-Done
Many students start a question confidently but leave it incomplete due to poor time planning.
How to avoid it:
Try to Attempt
- All 3 Markers questions 1st followed by
- All 4 Markers questions 2nd and then
- All 6 Markers
- 20 Marks MCQs may be easily attempted after completion of 60 Marks Descriptive paper.
- Time allocation is approx. 2 Minutes for each 1 Mark means
Marks of Question Approx. Time of Completion
- 3 Markers 6 Minutes to Complete
- 4 Markers 8 Minutes to Complete’
- 6 Markers 12 Minutes to Complete
So, keep a buffer of 10–15 minutes for review.
9. Forgetting Formats and Headings
Marks are deducted when:
• Proper titles are missing
• Accounts are not labelled correctly
How to avoid it:
Revise formats regularly – especially for Partnership and Company Accounts.
10. Confusion in Partnership Adjustments
Errors often occur in:
• Admission of a partner
• Retirement or death adjustments
• Goodwill calculation
How to avoid it:
Practise step-wise questions and revise journal entries thoroughly.
11. Incorrect Journal Entries
Even one wrong journal entry can affect multiple answers.
How to avoid it:
Understand the logic behind each entry instead of memorising blindly.
12. Ignoring Theory Questions
Students focus heavily on numericals and underestimate theory-based questions.
How to avoid it:
Prepare definitions, reasons, and short explanations properly – these are scoring and time-efficient.
13. Not Revising Mistakes from Tests
Repeating the same mistakes across tests is a major reason for stagnant scores.
How to avoid it:
Maintain a mistake notebook and revise it weekly.
14. Overconfidence in “Easy” Chapters
Students often skip revision for chapters they find easy, leading to careless mistakes.
How to avoid it:
Revise all chapters evenly. Easy chapters are scoring only when answered perfectly.
15. Lack of Evaluated Practice
Practising without feedback limits improvement.
How to avoid it:
Attempt evaluated tests to understand:
• Where marks are lost
• How answers are checked
• How to improve presentation
