The final week before your IB Maths exam: what to do (and NOT do)

The final week before your IB Maths exam: what to do (and NOT do)

With your IB Maths exam just days away, the pressure is on. I have seen students in my classroom for over a decade face this exact moment. Some students approach this final week effectively, while others fall into traps that hinder their performance. This article outlines what I believe are the most productive strategies, and what to avoid, in these critical days leading up to your exam.

My goal is to help you feel prepared and confident. This is not the time for panic or last-minute cramming of new material. It is a period for consolidation, strategic review, and mental preparation. Let's make sure your hard work throughout the year pays off.

What to DO in the final week

1. Targeted Revision, Not Rereading

Many students make the mistake of simply rereading their notes from cover to cover. This is inefficient. At this stage, you should know the content. What you need to do is identify and address your weak points. I always tell my students to focus their energy.

How do you identify weak points? Review your past tests, quizzes, and practice papers. Look for questions you got wrong, or areas where you felt unsure. For example, if you consistently struggled with optimization problems involving derivatives like finding maxima and minima for functions such as $f(x) = x^3 - 3x$, dedicate time to that specific topic. If calculating probabilities using the binomial distribution, $P(X=k) = \binom{n}{k}p^k(1-p)^{n-k}$, is still fuzzy, focus there.

Use your study notes or your textbook's index to locate specific sections quickly. Work through a few problems from each of these identified weak areas. Do not spend hours on topics you already master. If you are strong in integration by parts for HL Analysis and Approaches, for instance, there's no need to spend significant time reviewing $\int u \, dv = uv - \int v \, du$. Focus on what challenges you.

2. Practice with Past Papers – Strategically

Past papers are invaluable. However, how you use them in the final week is critical. Do not attempt a full three-hour paper every day. This leads to burnout and, if you perform poorly, can reduce confidence. Instead, use past papers to practice specific question types and to manage your time.

I recommend selecting specific sections or question types from past papers. For instance, if you're an AI SL student and struggle with financial maths, specifically compound interest formulas like $FV = PV(1 + \frac{r}{100k})^{nk}$, gather all financial maths questions from the last five years of Paper 2s and work through them. If you're an AA HL student and find vector geometry challenging, specifically finding the angle between two planes given their normal vectors $\vec{n_1}$ and $\vec{n_2}$ using $\cos\theta = \frac{|\vec{n_1} \cdot \vec{n_2}|}{||\vec{n_1}|| \cdot ||\vec{n_2}||}$, go through those questions.

Practice under timed conditions. Set a timer for the allocated time for a specific question or section. This builds speed and stamina. My students often find this a revelation – they realize they understand the content but struggle with the pace. It is also an excellent way to consolidate your knowledge of the use of your calculator for exams.

3. Master Your Calculator and Formula Booklet

Your graphing calculator is a powerful tool, but only if you know how to use it efficiently. In the final week, ensure you are absolutely proficient with its key functions relevant to your course. For example, for AI students, setting up and solving systems of equations, using the financial solver, or performing regression analysis on data sets. For AA students, graphing functions, finding derivatives, integrals, or solving complex equations numerically.

Likewise, your IB Maths Formula Booklet is your best friend. Know it inside out. Understand what formulas are provided and, more importantly, what isn't. I've seen students waste precious minutes searching for a formula that isn't there, or overlooking one that is. Practice locating formulas quickly. For instance, knowing where to find the volume of a cone $V = \frac{1}{3}\pi r^2 h$ or the sum of an arithmetic series $S_n = \frac{n}{2}(2u_1 + (n-1)d)$.

What NOT to do in the final week

1. Avoid Learning New Material

This is perhaps the most crucial "don't." The final week is not the time to tackle a topic you have completely avoided or never understood. Trying to cram complex new concepts like hypothesis testing for HL AI (e.g., $p$-values and critical regions) or understanding the nuances of Maclaurin series for HL AA ($\sum_{n=0}^{\infty} \frac{f^{(n)}(0)}{n!}x^n$) in the last few days will likely lead to frustration, overwhelm, and a decrease in confidence in what you already know. Focus on solidifying existing knowledge.

2. Do Not Compare Yourself to Others

Everyone's revision journey is different. Some students appear calm and collected, others are visibly stressed. Resist the urge to compare your progress, your understanding, or your revision schedule with your peers. This can be demotivating and unproductive. Your focus should be entirely on your own preparation. I tell my students that this is their journey, their exam. Focus on what you can control.

3. Do Not Overwork Yourself

Burning the midnight oil every night is counterproductive. Your brain needs rest to consolidate information and to perform optimally. Aim for regular, sufficient sleep. Pulling all-nighters will impair your cognitive functions on exam day, making it harder to recall information, solve problems, and stay focused. Schedule breaks during your study sessions. Step away from your desk, get some fresh air, eat healthy meals. Physical well-being directly impacts mental performance.

4. Do Not Neglect Other Subjects

While Maths is important, it is only one component of your IB Diploma. Giving disproportionate attention to Maths at the expense of your other subjects can lead to an imbalance and additional stress. Maintain a balanced revision schedule across all your subjects. This holistic approach will ensure you are performing well across the board, not just in Maths.

Final Thoughts

This final week is about refining, not rebuilding. Trust the process you've followed throughout the year. Use these days to consolidate your strengths, strategically address your weaknesses, and ensure you are physically and mentally ready for the challenge. Remember to breathe, stay calm, and believe in your abilities.

You have put in the work. Now it is time to demonstrate what you know. Good luck!
