I have been working as a Business Central technical developer for about 1.5 years, and I’m planning to take the Business Central Developer Associate certification (MB-820). I feel it’s the right time to earn this certification.

For those who have already taken the exam, I’d appreciate your advice: My exam is scheduled in 5 weeks, but I only have 4 weeks available to prepare.

How should I structure my study plan to make the most of my preparation time?

I’m especially interested in any tips on the most important topics to focus on, resources you found helpful, and strategies for effective last-minute preparation. I’m open to any recommendations.

Hi

Great timing, I just passed MB-820 which is a solid next step for someone with technical experience in Business Central. With 4 weeks to prepare, you’ll want a focused, structured plan that balances theory, hands-on practice, and mock testing.

Here’s how I’d recommend structuring your study:

Week 1: Foundation & Environment Setup

Review Business Central architecture, deployment models, and app structure

Set up your AL development environment with Visual Studio Code

Explore Microsoft Learn’s MB-820 Study Guide

Suggested modules:

Install and configure the development environment

Understand the update lifecycle

Week 2: AL Objects & Page/Table Extensions

Focus on tables, pages, enums, reports, and XMLports

Practice building and extending objects

Key topics:

Page types and layouts

Report design and layouts

XMLport configuration

Reference: Develop by using AL objects (35–40%)

Week 3: AL Language & Development Tools

Deep dive into AL syntax, triggers, events, and interfaces

Practice writing test codeunits and using the Test Toolkit

Explore telemetry and debugging techniques

Suggested modules:

Work with codeunits and events

Implement telemetry

Week 4: Integration & Mock Testing

Study API development, OData, and REST integrations

Build a sample extension that connects to an external service

Take multiple practice exams to identify weak areas

Recommended resource: EduSum MB-820 Practice Tests

Exam Tips

The exam has 40–60 questions, 120 minutes, and a passing score of 700/1000

Focus heavily on AL object development and integration topics

Use the Exam Sandbox to get familiar with the interface

I don't know if the current questions have been updated. I took the exam during the Beta test because I can use MS Learn to search during the exam. As long as I have enough time, I believe you can pass the exam.
For other less popular knowledge points, you can learn some of the following keywords.

Technologies for application lifecycle management (ALM), including source control management (SCM) and continuous integration and continuous delivery (CI/CD).

Substitute a report

Override entitlements with inherent permissions

Use a query to create a report

Create an onboarding checklist

Test applications in Business Central

Install and run the Test Toolkit

Develop test codeunits and procedures

Monitor and analyze telemetry

Configure telemetry

Create custom telemetry signals

Thanks.

Use Microsoft Learn and do practice as much as possible.

Note that you can still open and browse Microsoft Learn while doing the exam.

I have some resources and practice dumps (though I’m not sure if it’s okay to mention this on a Microsoft platform). I’m using them as test exams along with the Microsoft Learn platform to prepare for my certification. If you're interested, I’d be happy to share the same dumps my friend used as practice — he passed his exam just last month.
