Writing **assumptions** is important for getting full marks in CPA Canada cases, specifically in the **quantitative (quant) **type of AOs. In this guide, you’ll learn how to write assumptions the correct way, with tips on mastering this aspect of the case writing.

**Are assumptions necessary?**

Assumptions are necessary whenever there are uncertainties in quants (often there are lots!). It’s rare that you’re given a quants AO where all numbers are straightforward and there are no estimates or doubts. For this reason, you should **write assumptions **for every quants AOs. This is even more important for PM elective and CFE.

Below is an example from a recent CFE Day 1 case. You’ll see that it requires providing financial implications or quant considerations, like assumptions, as part of the marking rubric:

Below is an example of how assumptions could be written for Day 1:

You’ll notice that:

- It’s point form
- There are only 4 bullets (3-4 assumptions is acceptable)
- Unknown and uncertainties are included
- Other considerations, such as constraint, is included

So in summary, you should always write assumptions when you’re solving quants. Keep it point form, only a few bullets, and include any other considerations that are relevant, like constraints, user preferences, company objectives.

**What about CFE Day 3?**

Similar to CFE Day 1, assumptions are needed in CFE Day 3 quants whenever there are unknowns or uncertainties. Although it’s not a separate MPI (minimum proficiency indicator) in the Feedback Guide, it’s required when you have calculations that have uncertainties.

Below is an example from a CFE Day 3 case Feedback Guide:

Below is how you would write assumptions for this case:

The same rules apply towards CFE Day 2 common MA AOs, PM elective, Tax elective and Core 2. Write assumptions similar to above to support your quants and ensure you get a C.
