​​Dear IB Math AA SL/HL Students,
As the September examination approaches, it’s crucial to familiarize yourself with the formula booklet, which will be an essential tool during the exam. How you plan to use this booklet can significantly impact your performance. With just a few days left, take the time now to get to know your formula booklet inside and out to avoid wasting precious time searching for the right formula during the exam.

Here are two key steps to ensure you're confident with the necessary formulas:

Formulas Not in the Formula Booklet:
Identify the formulas that are essential but not included in the booklet. You will need to memorize these.

Formulas Present in the Formula Booklet:
a) For SL Students:
o Become well-acquainted with the specific page numbers where formulas for each SL syllabus topic—Number & Algebra, Functions, Geometry & Trigonometry, Probability & Statistics, and Calculus—are found.

b) For HL Students:
o Familiarize yourself with the page numbers where formulas common to both the SL and the HL streams for each topic—Number & Algebra, Functions, Geometry & Trigonometry, Probability & Statistics, and Calculus—are located.
o Identify the syllabus areas covered exclusively in the HL curriculum.
o Memorize the page numbers where HL-specific formulas can be found.

In summary, make sure you know the formulas not provided in the booklet and become thoroughly familiar with the booklet itself.

Wishing you all the best for your upcoming examination!

​​Dear Students,
Many of you get confused when differentiating expressions like 3x + 2. You know the derivative of a constant (like 2) is 0, but you might wonder about 3 in 3x. Some mistakenly think that since the derivative of a constant is 0, the entire term 3x becomes 0. This is incorrect.
The rule says the derivative of a constant is 0, not the derivative of every number. ‘Constants’ are stand-alone numbers (like 2 in 3x + 2), but ‘coefficients’ (like 3 in 3x) are numbers multiplied by variables. Coefficients remain unchanged during differentiation.
For example, in 3x, the derivative is calculated as follows:
• The derivative of x is 1.
• The coefficient 3 remains the same, so the derivative of 3x is 3 × 1 = 3.
To understand this better, think of 3x as x + x + x. The derivative of x is 1, so the derivative of x + x + x is 1 + 1 + 1 = 3.
Similarly, if you had an expression like 2 sin(x) cos(y), the number 2 is the coefficient and stays unchanged, while you differentiate the trigonometric functions based on their respective rules.
In summary: the derivative of a constant is 0, but coefficients are not constants on their own—they stay unchanged during differentiation.
Happy Learning!

​​Dear IB Math AA Finalists,
For those preparing for the May 2025 board examinations, your first mock exam is scheduled for January. This means it's time to kickstart your preparations in earnest. Consistent and focused practice is key to success, so start incorporating regular problem-solving into your routine.

This advice isn’t just for the finalists—it's equally important for all IB Math AA students. Regular practice is essential for building a strong foundation.

However, practice doesn’t mean simply reading through questions and their corresponding mark schemes. While this approach might make the solutions seem straightforward and obvious, solving problems in real time is often far more challenging. Even with the formula booklet at hand, you may find yourself stuck when attempting a question for the first time.

Here’s my suggestion:
Take the time to think deeply about each problem. Analyze it carefully and try to identify an appropriate method for solving it on your own. While this approach may feel slower and limit the number of questions you solve initially, it is far more effective in helping you grasp the concepts. Over time, this deliberate practice will strengthen your problem-solving skills, and you’ll find yourself solving questions on that topic with much greater ease.
Consistency and thoughtful effort will pay off. Start now, and you'll be well-prepared when the exams come around.

Wishing you all the best in your preparations!

​​Dear IBDP Finalists,
Wishing you all the very best for your upcoming examinations!

You’ve worked hard over the past two years of your IBDP journey, and you are well prepared for this final step. Believe in yourself, stay calm, and approach the exams with confidence. Remember to get a good night’s sleep before each paper, read every question carefully, and check your answers thoroughly—especially in your Math papers.

As an IB Math AA HL teacher, I'd like to offer a few final tips specific to the Mathematics exams:

Before and During the Exam:

1. Do not confuse inverse function notation with that of the first derivative notation of a function.
2. Remember, f^(n) (x) represents the n-th derivative of the function.
3. Memorize basic formulas—relying on the formula booklet for every small thing can waste time.
4. Be familiar with your formula booklet. Know the page numbers where each section’s formulas are located. HL students, especially, should know where the HL-specific formulas are.

Time Management:

5. Spend no more than 1 minute per mark. For instance, a 6-mark question should ideally take around 6 minutes.
6. If stuck, move on. Don’t spend more than half the time allotted for a question trying to figure it out. You can return to it later after completing the rest of the paper. This will save you some time for answering other questions.
7. You do not need to solve every question to get a Level 7. If you come across a difficult one (even a high-mark question), don’t panic—stay focused. Losing concentration often leads to unnecessary mistakes.

Answer Writing and Review:

8. Always check your answers before moving on to the next question—you may not get time later.
9. If you decide to revise an answer, don’t strike out the first version until you’ve completed the second one. You might still earn partial marks.
10. After writing the new solution, do strike out the old answer. If both answers are present, the examiner might consider the incorrect one.

Graphs:

11. When drawing graphs, make sure they stay within and cover the given domain and clearly show endpoints (label coordinates if possible).

Exam Strategy:

12. Avoid reading the entire paper at the start of the exam. It can waste valuable time and may shake your confidence if you encounter a tough question early on.

Stay composed, stay smart, and give it your best. You've got this!
Warm regards,
Nilanjana Sanyal.

​​Dear IBDP May 2025 Finalists,
Congratulations on reaching the end of your examinations! (Though I understand that in some countries, Paper 3 may still be ongoing.)
This year’s session has certainly come with its share of challenges. There’s been some frustration, especially regarding the Physics, Spanish, and most notably, the Math papers. Many students found Math AA HL Papers 1 and 2 particularly difficult. However, the good news is that Paper 3 was more approachable for most, and it could significantly boost your overall grade. For those who were uncertain about securing a Level 6, Paper 3 might just make that possible.
To those considering a retake in the November 2025 session: please think it through carefully. Retaking an exam always carries an element of risk. There's no guarantee that the November paper will be easier or more favorable than the one you just attempted. Moreover, once you opt to retake, your May exam results for that paper will be cancelled and replaced with the November result, regardless of performance.
Make your decision with full awareness and confidence—and remember, your efforts so far have already taken you a long way. Wishing you all the best as you await your results!
Warm regards,
Nilanjana Sanyal

​​Dear Parents of IBDP Beginners,

Mathematics is a compulsory component of the IBDP curriculum. Many students who aspire to pursue STEM-related fields often consider choosing IB Mathematics: Analysis and Approaches (AA) at the Higher Level (HL). However, it’s important to understand that STEM is a broad area of study, encompassing a wide variety of courses. Even within engineering alone, there are numerous specializations, and a vast number of universities around the world offer these programs.

While it’s true that top-tier universities in the UK and US often require a Level 7—or at least a Level 6—in AA HL, it is equally true that many other reputable institutions accept a Level 7 in Applications and Interpretation (AI) HL. Therefore, choosing the right Math course should not be based solely on ambition, but also on a realistic understanding of your child’s strengths in Mathematics.

If your child has received a Grade B in IGCSE Mathematics, it is wise to think carefully before selecting AA HL. The jump from IGCSE Extended Mathematics to IBDP Math AA HL is significant, and students need to be well-prepared for the challenges it presents. This is not meant to discourage anyone, but rather to present the facts clearly. In my view, achieving a Level 7 in AI HL is more advantageous than receiving a Level 5 in AA HL—especially when applying to universities. But this does not imply that Level 5 students do not have any hope. With a Level 5 in AA HL, you may still have the opportunity to pursue a STEM-related field at selected universities around the world.

Make your decision thoughtfully, keeping your child’s academic strengths and long-term goals in mind.

Wishing your children every success in their IBDP journey and beyond!

Warm regards,
Nilanjana Sanyal.

​​IBDP May 2027 AA HL Beginners — A Message for You!

First things first — if you’ve chosen Mathematics: Analysis & Approaches HL, give yourself a well-deserved round of applause!

You’ve opted for the most challenging and rigorous of the four IB Math streams. This decision wasn’t meant to be casual — and hopefully, it wasn’t. It should have been taken with serious thought, a clear goal, and an even clearer dream. And if that’s the case — congratulations on your bold choice!

In India, Grade 11 classes are already underway, while in many other parts of the world, they'll be kicking off in a couple of months. So tell me — how are you feeling about your AA HL journey?

Some of you have already teamed up with tutors and are attending their lessons with focus and consistency. Others are still weighing things, trying to figure out if they can power through this path independently. Either way — you all have something in common: this decision was made because of a dream.
A dream stream.
A dream university.
A dream career.
A dream version of yourself.

Let that dream fuel your determination, every single day, until the final paper of the IBDP May 2027 exam.

There will be days when you’ll feel like you haven’t moved forward. That’s okay. But what you must avoid is stepping backward. You can’t afford to lose touch with what you’ve already learned.

Practice Math every single day.
Yes, even on the busy ones.
It’s alright to miss a day occasionally — but let it remain occasional. If skipped too often, you’ll realize down the line that much of what you knew has slipped away.

So here’s your AA HL mantra:
Progress is non-negotiable. Backward steps are not allowed.

You’re in this for a reason. Now go prove to yourself that you belong here.

Happy AA HL learning!

​​Dear IBDP Beginners,
Are you taking Math AA HL as one of your subjects? How confident are you in Math? How did you perform in your IGCSE board exams or the IB MYP assessments?

Lately, I’ve noticed a growing number of students with a Grade B in IGCSE Math choosing to pursue Math AA HL. This post isn’t meant to discourage you—far from it. Instead, it’s a gentle reminder to honestly assess where you currently stand in Mathematics and what steps you’ll need to take for moving forward.

A Grade B in IGCSE typically suggests that there may be gaps in your foundational understanding of Math concepts. Despite this, you've opted for the most rigorous math course in the IBDP. Why? Because you have ambitious goals—you’re aiming for admission into a reputed university and want to pursue a competitive course that aligns with your dream career.
There’s absolutely nothing wrong with that. In fact, it’s commendable. But it’s important to recognize that you might need more time and support to build the strong mathematical foundation that others—perhaps those with an A or high A—might already have.

So here’s what you can do:
Start early. Don’t wait for the school to begin.
Get guidance. Find a good tutor who understands the demands of AA HL.
Increase your support hours. Consider adding at least one extra hour of tutoring each week beyond the usual.
Practice regularly. Daily Math practice is non-negotiable.
Clarify doubts immediately. Talk to your teacher or tutor—don’t let confusion pile up.

Remember, school lessons and tutoring can only take you so far. It’s your consistent effort, your daily practice, and your determination that will ultimately shape your success.
Stay committed, work hard, and you’ll absolutely be on track to achieve your dream future.

Happy AA HL learning!
