Start with one weak module
Because the course is organised by modules, you can unlock the part you need most instead of buying or starting the entire 100-session course from the first day.

If the IB exams are getting close and HL AA Mathematics feels overwhelming, the answer is not to panic through more random questions.
You need a direct path: rebuild the weakest module, practise exam-standard questions, and turn the effort you still have into marks.

When you fall behind in IB HL Mathematics, the feeling is familiar. There are too many topics, too many past-paper questions, too many videos, too many notes, and too little time.
So the instinct is to do more. More questions. More tuition. More searching. More late nights. More trying to catch up on everything at once.
But when the exam is only a few months away, effort has to become more targeted. The question is no longer, “How do I study all of HL Math again?”
The better question is: “Which module is costing me the most marks, and what is the fastest responsible way to rebuild it?”
100 Days of Math was built for that kind of recovery. Not vague motivation. Not random drilling. A focused path from foundations to exam-standard practice.
At this stage, the goal is not to do everything. The goal is to make your next block of effort count.
When time is short, you need structure. 100 Days of Math lets you choose a module, rebuild the foundations, practise the key concepts, and move towards exam-level questions with less wasted effort.
Because the course is organised by modules, you can unlock the part you need most instead of buying or starting the entire 100-session course from the first day.
Each chapter begins with the prerequisite ideas needed for that topic, so you are not forced to jump straight into difficult questions while old gaps remain hidden.
You practise questions designed around IB-style reasoning, command terms, problem-solving steps, and the level of thinking needed for the actual exam.
Practice is guided by concept weightage, chapter distribution, exam patterns, and teacher experience, so you focus on high-value concepts and bridging ideas.
Chapter notes, worked solutions, review, and the dashboard help you see what you know, what still needs work, and what to focus on next.
Two weeks will not magically replace two years of learning. But used properly, it can become a serious recovery block for one weak module.
Start each chapter from the prerequisite ideas instead of pretending the basics are already secure.
Short concept videos explain one idea at a time before you put it into practice.
Move beyond basic textbook drills into questions closer to IB exam expectations.
See not only the final answer, but the reasoning and links between steps.
Learn Ti-Nspire workflows where they matter for Paper 2.
Use concept mastery and recommendations to focus on what still needs review.
