With case study exams always looming on the horizon, I’ve been reflecting on my own case study journey.
The first time I approached a case study exam, I felt a false sense of security. Coming off the back of the objective tests where you have to memorise formulas, calculations, and dry rules, the case study felt like a relief. You get the company background weeks in advance, there are no heavy calculations under exam pressure, and it feels much more practical.
So, what did I do? I relied way too much on the pre-seen document without actually learning how to use it.
I spent weeks reading and highlighting the 30+ page pre-seen document until I could practically recite the fictional company’s financial stats from memory. But when I sat down in front of the exam screen, I panicked. I knew all about the company, but I didn’t know how to answer the actual questions in front of me.
If you are currently preparing for an upcoming case study sitting, here are the four biggest pre-seen mistakes I made and how you can avoid them before exam day.
#1 – Treating the pre-seen like a novel
During my first attempt, I read the pre-seen document from top to bottom four times. I highlighted page after page with bright highlighters. It felt like I was working hard, but it was completely passive.
Knowing what the company does doesn’t get you marks; knowing where the risks and opportunities lie does.
Instead of just reading through it alone, I started using Astranti’s pre-seen analysis pack. Having expert tutors break down the strategic threats, financial ratios, and industry context helped me see the document through an examiner’s eyes. Suddenly, the background story became clear, with potential exam triggers.
#2 – Memorising answers before reading the trigger
In the exam, CIMA gives you a “trigger” scenario a new development, a crisis, or a business proposal that builds on the pre-seen background.
On my first attempt, I had pre-prepared answers in my head for scenarios I thought would come up. When a question appeared on a similar topic, I dumped all my pre-memorised knowledge onto the page.
Result? I scored poorly because I answered the question I wanted to see, not the question CIMA actually asked.
Rule of thumb: Every single paragraph you write in the Case Study must reference the specific scenario in the exam prompt. If your answer could apply to any random company in that industry, you aren’t giving business advice; you’re just writing a textbook dump.
#3 – Ignoring the strategic role (The “Who am I?” test)
A major key to passing CIMA’s case studies is the heavy emphasis on finance business partnering and role simulation.
Whether you are sitting OCS, MCS, or SCS, you are taking on a specific persona in that company (e.g., finance officer, finance manager, or senior accountant).
In my early practice, I wrote answers like a student taking a test. I used phrases like “the textbook says…” or “according to theory…”
To pass, you have to talk like a colleague advising management:
- Bad: “IFRS 16 states that leases must be recognised on the balance sheet.”
- Good: “Looking at our current vehicle fleet lease arrangement, bringing these assets onto our balance sheet will impact our gearing ratio, which could concern our bank lenders.”
#3 – Leaving mock practice until the final days
I used to treat mock exams like the final step of revision, something you only do when you feel “ready.” The problem? You will never feel 100% ready.
By delaying mock exams until the last minute, I missed out on the most valuable part of revision: timing practice and structure.
When I prepared for my resit, I started sitting timed mock exams early. Doing them under strict time constraints forced me to practice structuring my answers under pressure and typing at speed. Getting feedback on my mock attempts showed me exactly where I was being too vague before the real exam day arrived.
Final Thoughts
The case study isn’t an exam where you can cram facts the night before. It’s a test of how well you can apply what you know to help a real-world business navigate a problem.
If you’re sitting your exam soon, take a breath, focus on answering the specific questions on the screen, and remember to think like a finance business partner!
