One of the biggest advantages of speaking to successful students is learning not only what they did right, but also what they would avoid if they had to sit the exam again.
Every exam sitting sees capable students fail—not because they lack knowledge, but because they make avoidable mistakes during preparation or on exam day.
Below are the most common mistakes shared by passed students and frequently observed by tutors at Keystone Academia.
Mistake 1: Reading the Preseen Only Once
Many students download the CARTN preseen, read it over a weekend, and then focus entirely on E2, P2 and F2.
This is one of the biggest mistakes you can make.
The preseen should become your daily reading material.
Each time you revisit it, you notice:
- New business risks
- Financial issues
- Stakeholder concerns
- Strategic opportunities
- Operational challenges
By exam day, you should know the company almost as well as your own workplace.
Mistake 2: Ignoring the Industry
The examiner expects you to understand more than just the company.
You should also understand the packaging industry.
Spend time researching:
- Sustainable packaging
- Supply chain disruptions
- Manufacturing efficiency
- Raw material price volatility
- Environmental regulations
- Recycling initiatives
- Automation in manufacturing
- Customer expectations
A little industry knowledge helps you produce more commercial answers.
Mistake 3: Writing Generic Answers
One of the fastest ways to lose marks is writing answers that could apply to any business.
For example:
“Management should reduce costs.”
That advice is too generic.
Instead write:
“CARTN should review its procurement strategy and negotiate longer-term supplier contracts to reduce exposure to fluctuations in raw material prices while maintaining product quality.”
Always relate your recommendations back to CARTN.
Mistake 4: Forgetting the Requirement
Many students write everything they know about a topic.
The examiner only awards marks for answering the question asked.
Before typing, identify the action verb.
Examples include:
- Evaluate
- Recommend
- Discuss
- Advise
- Assess
- Analyse
- Explain
- Justify
Your answer should match the action verb throughout.
Mistake 5: Weak Conclusions
Do not finish your answer suddenly.
Summarise your recommendation clearly.
For example:
“Based on the financial and operational benefits, investing in automated production equipment is likely to improve efficiency and profitability. Management should proceed after completing a detailed investment appraisal and implementation plan.”
Professional conclusions strengthen your response.
Mistake 6: Ignoring Stakeholders
Every business decision affects someone.
Ask yourself:
- How will shareholders react?
- What will customers think?
- How are employees affected?
- Will suppliers benefit?
- What are the regulatory implications?
Balanced answers usually score higher.
Mistake 7: Poor Time Management
Many students spend too long on the first task.
Later questions then receive rushed answers.
Remember:
Every requirement carries marks.
Do not sacrifice later questions trying to perfect your first response.
Move on when your allocated time has finished.
Mistake 8: Not Reviewing Mock Feedback
Completing mock exams is only half the process.
The real improvement happens when you analyse your feedback.
After every mock ask:
- Which marks did I lose?
- Why?
- How can I improve?
- Did I answer the requirement?
- Did I support my recommendations?
Improvement comes from reviewing mistakes.
Mistake 9: Focusing Only on Technical Knowledge
Students often spend weeks studying IFRS standards while neglecting commercial thinking.
Remember:
The examiner wants a Finance Manager, not an accountant reciting standards.
Always connect technical knowledge to:
- Business performance
- Profitability
- Risk
- Strategy
- Decision making
Mistake 10: Losing Confidence Before Exam Day
Many students consider postponing the exam during the final week.
This feeling is normal.
Trust your preparation.
If you have:
- Studied consistently
- Completed mock exams
- Reviewed the CARTN preseen
- Understood the business
then you are far better prepared than you think.
Confidence comes from preparation.
