Top 5 Mistakes Students Make in the CM1 Exam – And How to Avoid Them

Cracking the CM1 Actuarial Exam isn’t just about hard work – it’s about working smart. At SMONK, we've guided hundreds of students through this demanding paper, and one thing stands out: many failures happen not due to lack of knowledge, but due to poor exam strategy.

If you're preparing for the CM1 exam (or retaking it), here are the Top 5 Mistakes we’ve observed – and, more importantly, how to avoid them and set yourself up for success:

1. Underestimating Theory

The Mistake:

Most students treat CM1 like an Excel-heavy paper. While Paper B gets a lot of attention, the theoretical foundation in Paper A is often ignored – especially chapters like Chapter 2 (Compound Interest Functions), Chapter 8 (Loan Schedules), and Chapter 24(Profit Testing).

Why It Hurts:

Theory accounts for 50% of your marks. Weak conceptual clarity can cost you in derivation questions, long-form explanations, and even in Excel-based logic.

Fix:

Dedicate at least 40% of your study time to theoretical topics. Use concept maps, write your own summaries, and test yourself on derivations weekly.

2. Practicing Excel Without Exam Conditions

The Mistake:

Solving Excel questions casually at home, with access to unlimited redos, online resources, or without time pressure.

Why It Hurts:

Paper B is time-bound and demands sharp thinking under pressure. You might perform well during practice, but falter in a real-time setting.

Fix:

Simulate exam conditions every time you practice:

  • Set a strict timer
  • Limit yourself to 1 or 2 attempts
  • Avoid switching to notes or YouTube

This helps build your speed, accuracy, and confidence.

3. Ignoring Past IAI/IFoA Paper Trends

The Mistake:

Skipping past papers or solving them too late in the preparation process.

Why It Hurts:

Every examiner has a pattern. Repeated question formats, common chapters, and typical derivations give you critical insights into what to expect.

Fix:

Solve at least 5 full past papers from both IAI and IFoA – for both Paper A & B. Analyze the marking scheme and identify your weak areas after each attempt.

4. Not Revising Formulas Weekly

The Mistake:

Learning formulas once and assuming they’ll stick.

Why It Hurts:

In CM1, you’re expected to apply formulas instantly – in Excel and in written papers. Without regular revision, students often blank out or make critical errors.

Fix:

Use spaced repetition tools like Anki or traditional flashcards. Create a habit: every Sunday = Formula Revision Day. It takes just 30–45 mins but pays off big.

5. Waiting Too Long to Start Mocks

The Mistake:

Delaying mocks till the entire syllabus is covered.

Why It Hurts:

Mocks aren’t just to check your preparation – they build your preparation. Waiting till the end leaves no room for improvement.

Fix:

Start your first mock by Week 4 – even if you’ve completed only 50% of the syllabus. Use it as a diagnostic tool, and build from there.
