A-Level Accounting Mistakes and How to Fix Them
Your figures looked right. The marks still went missing. This frustrates almost every Accounting student at some point.
Most lost marks come from a short list of repeat errors, not from missing knowledge. Spotting these A-Level Accounting mistakes early is the fastest way to lift your grade.
TutorGem’s A-level tutoring sees the same patterns every year. This guide lists them and gives a simple fix for each.
Why Accounting Marks Disappear Quietly
Accounting looks like pure calculation, so students assume a wrong answer is the only way to lose marks. In reality, marks vanish through small slips in method and presentation.
What the 2025 Grade Boundaries Show
Published 2025 AQA grade boundaries for Accounting set the A* boundary at 183 raw marks, A at 158, B at 135, and E at 68. These are raw marks, so a student does not need a perfect paper to earn a top grade.
This matters. Every method mark you save moves you closer to the next boundary. Please check the latest figures on the AQA website, since boundaries change each year.
The Most Common A-Level Accounting Mistakes
Most errors repeat across papers. Learn the list and you can catch them in your own work.
Double Entry and Adjustment Errors
Reversing a debit and a credit is the classic slip. Forgetting year-end adjustments, like accruals, prepayments, and depreciation, is just as common.
Depreciation causes extra trouble. Students mix up straight line and reducing balance, or forget to adjust the asset’s cost.
Ratio Analysis Without a Conclusion
Many students calculate ratios correctly and then stop. Analysis questions reward a clear comment on what the figures mean for the business.
| Mistake | Why It Costs Marks | Simple Fix |
|---|---|---|
| Debit and credit reversed | Errors carry through every later step | Say the rule aloud before posting |
| Missing adjustments | Profit and balance sheet are wrong | Use a year-end adjustments checklist |
| Mixing depreciation methods | Wrong charge, wrong net book value | Write the method name at the top |
| No working shown | Method marks cannot be awarded | Show every step, even simple ones |
| Ratios with no comment | Analysis marks are missed | Add one sentence on what it means |
A Real Case: Showing the Working
One TutorGem student preparing for A-Level Accounting scored well on theory but kept dropping marks on long questions. His answers were often almost right.
His tutor noticed he skipped his working to save time. When one early figure was wrong, he lost marks on every later line, even where his method was correct.
Mark schemes often award marks for correct method even after an earlier slip. After he began showing every step, his practice scores rose by a full grade in six weeks.
A Simple Fix for Every Mistake
Fix one habit at a time. A short checklist beats long, unfocused revision.
Before you submit any question, check three things. Did you post debits and credits correctly? Did you apply every adjustment? Did you show your working?
Questions to Ask After Every Practice Paper
Which marks did I lose from small slips, not missing knowledge? Did I write a comment on every ratio?
These two questions reveal most repeat errors.
How a Tutor Helps
A tutor marks your work against the real mark scheme and shows exactly where marks slipped. This turns “careless mistakes” into a clear, fixable list.
TutorGem’s online tutoring matches you with an accounting specialist for your exam board, wherever you study.
