Custom IA Plans & Services
You start by filling out our detailed Custom IA Intake form. Our expert educators will review your topic and create a personalized plan (within your selected timeframe) explicitly structured around the IB Math rubric, giving you the exact formulas, structure, and data sources you need.
Absolutely not. A Custom IA Plan is strictly an educational outline and a roadmap. You must write the entirety of the IA in your own words and perform all your own calculations.
If you’ve already written a draft (or part of one) and want to know how it scopes against the IB rubric, you can use our IA Feedback Service. For $30, we will review your existing work, provide an estimated grade, and tell you exactly where you’re losing marks. It is ideal if you want a professional check before sending it to your teacher.
You upload your IA draft, and an IB expert will review it rigorously against the official IB Mathematical Exploration rubric. You’ll receive qualitative feedback, a projected score, and step-by-step instructions on improving it. It continues as many times as needed until your submission date.
Yes. Rush delivery (48 hours) is available for an additional $20. Urgent delivery (24 hours) is available for an additional $40. Contact us after purchase to arrange this.

General
All resources are created by qualified IB Mathematics teachers with over 10 years of experience teaching AA and AI courses at SL and HL levels.
Yes. All resources are designed for the current IB Mathematics curriculum. We update resources when the IB updates its assessment guidelines.
Currently, our Mock Exams, Workbooks, and standard IA resources are specifically tailored for Analysis and Approaches (AA) for both Standard Level (SL) and Higher Level (HL). AI-specific resources are in development and coming soon. However, our Custom IA Plan service can accommodate AI SL/HL students.
Free resources give you general advice. SamzHub gives you structured, teacher-created frameworks and expert feedback designed around exactly what IB examiners look for — not generic study tips.
