CBDA Study Plan: A 6-Week Schedule to Pass the IIBA Exam

A good CBDA study plan takes about six weeks at 8–10 hours a week if you already work with data or business analysis, and two to three months if you are new to the field. The IIBA Certification in Business Data Analytics (CBDA) exam has 75 scenario-based questions in 2 hours, so the plan below spends most of the time on the three domains worth 20% each and ends with timed mock exams.

Last verified: October 2026 (exam facts from IIBA's official CBDA and fees pages).

Who this CBDA study plan is for and how long it takes

This CBDA study plan is for analysts with some hands-on analytics work who want a fixed schedule instead of an open-ended reading list. IIBA's handbook describes the target candidate as someone with about two to three years of analysis work in business analytics, but the exam page lists no formal prerequisites.

How long people actually study varies:

The IIBA Sydney chapter notes that prior work on a BABOK study group or a core business analysis certification is very helpful. If you have neither, plan for the longer range and read our overview of the CBDA certification first.

What the exam weights mean for your schedule

The exam weights decide where your hours go. Three domains carry 60% of the score:

Analyze Data gets a little more time than its weight suggests because statistics is the topic many business analysts know least.

The 6-week CBDA study plan, week by week

The plan follows the order of the analytics process in the Guide: frame the question, get the data, analyze it, report it, act on it, then scale it across the organization. Each week has reading, notes, and practice questions.

Week 0 (one evening): baseline

• Take IIBA's free CBDA sample questions quiz. IIBA itself advises that a score under 80% means you should read its "Understanding Business Data Analytics" paper before going further.
• Download the CBDA Certification Handbook and skim the domain task lists.
• Book a tentative exam date six to seven weeks out. A date makes the plan real.

Week 1: Identify the Research Questions (20%)

• Read the Guide chapter on defining the business problem, the stakeholders, and the research question.
• Practice turning a vague request ("sales are down") into a testable question with a scope, a metric, and a decision owner.
• Read our article on framing a business problem as a research question.
• Do 15–20 practice questions on this domain only.

Week 2: Source Data (15%) and data quality

• Study data collection plans, sources, sampling, and how to judge if a data set is fit for purpose.
• Learn privacy and ethics basics: consent, minimization, and who may see which data.
• Use our guide to sourcing and validating data, then test yourself with the CBDA data quality questions.

Week 3: Analyze Data (16%)

• Cover data preparation, exploratory analysis, and the basics of modeling.
• Know the difference between descriptive, diagnostic, predictive, and prescriptive analytics. Adaptive US trainers name the confusion between these types as a frequent mistake.
• Review hypothesis tests, p-values, correlation, and regression at the level of interpretation. You need to read results, not calculate them by hand; the exam has no coding.

Week 4: Interpret and Report Results (20%)

• Study how to match the message, the visual, and the audience.
• Practice choosing chart types with the CBDA data visualization questions.
• Write a one-page summary of a real analysis from your own work: finding, confidence level, and recommended action.

Week 5: Business decisions (20%) and strategy (9%)

• Domain 5: how analysts turn findings into options, recommendations, and change plans.
• Domain 6: analytics operating models, data culture, talent, and governance. It is only 9% of the exam, so read it once and make a one-page summary.
• Take your first full timed mock exam at the end of the week.

Week 6: mock exams and review

• Take two or three more full mocks under exam conditions: 75 questions, 2 hours, no notes.
• After each mock, spend as long on review as on the test itself. Write down why each wrong option was wrong.
• Mix all domains with the CBDA scenario questions set.
• Book or confirm the exam when you score above 70–75% on two mocks in a row.

Study materials, official first

Use official IIBA material as the base and treat everything else as practice:

1. Guide to Business Data Analytics (IIBA). The exam is built on it. It is a members-only resource, which is one reason the exam fee includes a year of membership.
2. CBDA Certification Handbook (IIBA). Domain task lists and exam rules.
3. IIBA sample questions quiz and the "Understanding Business Data Analytics" and "Introduction to Business Data Analytics" papers.
4. A local IIBA chapter study group, if one runs near your exam date. Chapters such as Sydney and South Africa run them online.
5. A practice question bank with explanations for every option.

According to a 2023 Medium post by a candidate who passed in December 2022, mind maps and per-domain mock sets from a training course were the most useful parts of his preparation. A 2024 candidate story on Techcanvass reports the same: mind maps helped a software developer see how the topics connect.

How to practice on questions

CBDA questions describe a situation and ask what the analyst should do, or do first. Candidates and trainers agree that memorizing terms is not enough.

• Answer for business value. An Adaptive US article (October 2026) notes that several options often look technically correct, but only one serves the business goal in the scenario.
• Review wrong answers in writing. LN Mishra, a CBDA-certified trainer, recommends timed full-length tests followed by a review of every incorrect answer to find weak areas.
• Repeat full mocks. Adaptive US suggests three to five full mock exams with scores consistently above 70% before the real exam.
• Apply, do not memorize. Managing Projects the Agile Way (2025) advises applying data analytics concepts to scenarios rather than memorizing definitions.

Exam-day tactics

• Pace: 75 questions in 120 minutes is about 96 seconds each. Check that you have passed question 38 by the 60-minute mark.
• Read the last line first. Find out if the question asks what to do first, next, or best, then read the scenario.
• Eliminate. Remove options that skip a step in the analytics process, such as analyzing before the research question is agreed.
• Flag and move on. Do not spend more than two minutes on one question in the first pass.
• Remember the order. Many "what first" questions are answered by the domain order: question, data, analysis, report, decision.

After you pass, plan for upkeep. The CBDA is renewed every year with continuing development units, and Mufaddal Haidermota advises "Keep reading, keep learning because analytics is constantly evolving."

FAQ

How many hours do I need to study for the CBDA?

Most candidates with analytics experience need about 40–60 hours over four to six weeks. Newcomers to data analytics should plan for two to three months. Your baseline score on IIBA's sample quiz is a good guide: under 80% means start with the longer plan.

Do I need to know statistics or coding for the CBDA?

You do not need to code. You need to interpret common statistical results such as p-values, correlation, and regression output, and know which analysis fits which question. Spend extra time on the Analyze Data domain if statistics is new to you.

What is the passing score for the CBDA exam?

IIBA does not publish a passing score. Prep providers often quote about 70%, but that is an estimate. Aim for scores above 70–75% on several full mock exams before you sit the real one.

Is the Guide to Business Data Analytics enough to pass?

The Guide is the reference the exam is built on, so read it fully. Most candidates also use scenario-based practice questions, because the exam tests how you apply the Guide in situations, not how well you recall its wording.

How much does the CBDA exam cost?

As of October 2026, the exam costs $405 for non-members, with the first year of IIBA membership included, or $250 for existing members. A rewrite costs $195 for members and $350 for non-members. There is no application fee.
