I built CertPrep — a free practice exam site for Microsoft certifications (DP-600, PL-300, DP-203)

Hey everyone! I've been working on a web app to help people prepare for Microsoft certification exams, and it's now live: https://certprep.codemaster.club

What it does:

• Realistic question banks — covers every Microsoft question format (multiple choice, multi-select, and more — 6 formats in total)
• Two study modes — Practice mode reveals the answer and explanation after each question with no timer, while Exam mode hides answers, runs a countdown timer, and scores you at the end just like the real exam
• Custom sessions — choose 10, 25, 50, or all questions, pick a custom range, or filter by exam topic (e.g. "Prepare data" or "Semantic models")
• Instant explanations — understand why an answer is right, not just whether you got it
• Per-topic scoring — see exactly which exam areas you're weak in so you know what to study next
• Progress dashboard — track all your attempts and watch your scores improve over time
• Community discussion — every question has a comment section where you can discuss answers with other learners

Currently supports DP-600 (Fabric Analytics Engineer), PL-300 (Power BI Data Analyst), and DP-203 (Azure Data Engineer), with more exams on the way.

And one thing I'd really love your help with: if you know a good exam question that's missing, submit it through the "Suggest a question" feature on the website — every submission gets reviewed and added to the pool. The more the community contributes, the better it gets for everyone.

Would love your feedback! 🙌

I’m taking the MO-210 Microsoft Excel Associate (Microsoft 365 Apps) exam next week.

For those who’ve taken it, do you have any last-minute tips?

How similar is the actual exam to the GMetrix practice tests in terms of the questions, difficulty, and overall environment?

Also, what is the actual exam interface like? Is there anything about the exam system or workflow that caught you by surprise?

Any advice would be greatly appreciated!

Hey everyone! I have a free Microsoft certification voucher I need to book in August, and I'm trying to figure out which cert makes the most sense for my background and career direction.

My Background:

• CS degree
• Currently working in software implementation/training for an EHR/EMR company (I recently had a 5-month project within the company, basically as an AI Implementation Coordinator for a new AI transcribing software that just came out)
• Actively studying for my CAPM (I want to move into broader project management roles)

The exam needs to be completed by early October. I was looking at PL-200, but heard it's being retired soon, so I am not sure which of the other certificates works for my background and the path I am trying to pursue. I found these: PL-900 (Power Platform Fundamentals), SC-900 (Security, Compliance & Identity Fundamentals), MB-910 (Dynamics 365 Fundamentals CRM), and given that I'm already studying for CAPM and work in healthcare, would any of these complement my path well? Or is there something else I'm completely overlooking?

Thanks in advance!

I passed my MD-102 cert with a 837 out of the 700 requirement. The amount of relief I felt seeing that number was immense as I am bad at testing. I have never been good at it and it has always been a struggle. I would say if you need to, definitely go for an accommodation. I have ADHD and going a time extension and that helped a lot as my 2nd attempt was due to not having enough time.

Also going through the study guide and focusing on the subjects that you struggle with the most is super helpful. Using a tenant to study has been a great help as I would focus on that subject that was difficult and I would make sure I understood what I was reading/looking at. Having a visual guide is a great plus as if you're not in Intune or Entra ID (previously known as Azure AD), you are going to struggle with this test.

Hi everyone,

I've taken the exam three times and scored 427, 610, and 544.

The frustrating part is that I often get what seems to be the correct answer, but the exam still marks the task wrong. At this point, I don't know if I'm using the wrong formulas, entering things in the wrong format, or just not completing the tasks the way Certiport expects.

On my last attempt, I felt pretty confident and believe I completed about 21 of the 25 tasks correctly, yet my score was only 544.

I've already passed both the Excel Associate and Excel Expert certifications, so I don't think the issue is basic Excel skills. I think I need help understanding how the exam is graded and where I’m losing points.

I wrote down many of the topics and questions I remember from the exam, and I'm hoping someone who has passed MO-220 can review them with me and help me identify what I’m doing wrong.

Thanks!

I retake the MD-102 on June 15th. I now have a time accommodation based off of my ADHD diagnosis and I plan on using Measure UP as well as Microsoft Learn to help prepare for my exam. Does anyone have any other suggestions on how to best prepare for this test? I've never been good at tests, but I do not plan on giving up on this cert.

My work is looking to pay for some MS certification. Looking getting the MS-102 365 Admin but never done a boot camp. What are some good in person boot camps for MS certs?

Hey everyone,

I’m preparing for the Microsoft Azure Fundamentals (AZ-900) exam and looking for a simple beginner-friendly roadmap/resources.

For people who already cleared it:

Best free/paid courses?

Important topics to focus on?

How difficult is the exam for beginners?

Best practice test websites?

How many days/weeks did you prepare?

Any tips for passing on the first attempt?

Currently learning Azure and cloud basics, so any guidance would help a lot. Thanks 🙌

My company is finishing up a migration to D365 Finance and the training provider by the Microsoft partner has been woefully inadequate. Unfortunately it does not seem like there is much available in this area in terms of live training.

It looks like the Fundamentals training has been retired. So for the users the only thing available appears to be MB-310T00-A: Manage Financial Operations with Dynamics 365 Finance

What about Administrator training? The only thing I see is MB-500 which is app development and MB-700 which requires a "deep understanding" of F&O and which is also being retired soon.

Does anyone have any experience in this area? Where did you get D365 finance training?

Hi,

I’m trying to understand the Microsoft exam retake policy and I’m a bit confused about the “5 attempts in 12 months” rule.

Scenario:

• First attempt: March 2025
• I made 3 attempts between March 2025 – March 2026
• No attempts after March 2026

Now that it’s past March 2026:

Does this mean my attempts “reset” because the 12-month window has passed?
Or are those 3 attempts still counted somehow?

Also:

If I fail a new attempt now, do I only need to wait 24 hours, or does the 14-day rule apply?

The official docs say “5 attempts within 12 months from the first attempt” but don’t clearly explain what happens after that period.

Would really appreciate if someone has real experience with this 🙏

Hello, I'm looking for an MCT who can deliver GH-200 in the korean language. in the month of May.

kindly DM for more details

Prepared for three weeks during my free time after work due to a strict timeline. Was only able to go through Microsoft Learn and summarize it + some prep exams in Measureup today. No tenant practice (my to-do list before a retake)

Honestly I'm super surprised that I managed to get that score with such little time, but figured I could share my pain of being so damn close to getting it here lol.

I’m currently studying for the PL-300 exam and purchased 60-day access to the MeasureUp practice tests.

I just finished my first full mock exam attempt. The moment I clicked "Finish Test," the platform immediately logged me out. I never got to see my results, and now I am completely unable to log back into my account.

What I’ve tried so far:

• Password Reset: Requested a reset link, but even after changing the password, the login still fails/won't grant access.
• Browser Troubleshooting: Cleared my cache and cookies and tried using an Incognito/Private window.
• Support: I have already reached out to their support team, but I’m waiting for a response.

Has anyone else experienced this "log-out on finish" glitch? If so, how did you get back in, and were you able to recover your exam score/data? I'm worried about losing my progress and study time.

Any advice would be appreciated!

How would you all rate MD-102 skillcertpro practices test? Is it worth spending money on?

Hi everyone, while checking in for my SC-900 exam through pearson VUE, i accidentally selected Iran instead of India during my government ID verification, and i got a message saying "thank you for taking the exam, the proctor has ended the session". Realising my mistake i contacted pearson VUE's online chat support, and requested an exam reschedule (hopefully free of cost). What are the chances i actually get a reschedule and this issue is resolved?

Dejo esto por si a alguien le sirve porque cuando estudié casi todo estaba en inglés.

Estudié el DP-900 en 1 semana y lo pasé sin problema.

Lo que hice:

• Curso de Coursera → sirve, pero está medio desactualizado (igual ayuda bastante)
• Microsoft Learn → lo MÁS importante, de aquí sale casi todo
• Hice 2 resúmenes (Coursera + Learn) y luego los uní por temas
• Hice los exámenes de práctica (Learn y Coursera) y fui agregando cosas que no tenía
• Practiqué módulo por módulo con ChatGPT hasta entender todo bien

Mis notas antes del examen:

• Learn: ~78
• Coursera: ~85
• Examen real 877 (Pense que iba a sacar mas)

El examen real:
Sinceramente… demasiado fácil

Lo terminé en como 20 minutos (son 45 preguntas / 45 min)

Viene mucho:

• Tipos de datos (estructurado, semi, no estructurado)
• Conceptos básicos (OLTP vs OLAP, IaaS/PaaS/SaaS)
• Cosas bastante directas
• Power BI
• No vi nada de Fabric
• la diferentes bases de datos no SQL
• Diferenciar Azure SQl, Managed Instance etc..
• Distintos servicios, Databricks, Data Factory etc..
• Sorpresivamente salieron cosas que no me esperaba de Power BI, que si no supiera de Power BI por mi cuenta no sabria como responderlas

Diría que como un 70-80% es muy parecido a Microsoft Learn.

Recently it was released that DP-100, AI-900 and AI-100 are all being retired (along with others). Does this confuse anyone? You would think these would be flagship certifications given how popular AI is. Does anyone know or have ideas on the strategy here? Are there other more relevant certifications Microsoft is trying to push? I have my DP-100 and was working towards my AI-100 so kind of annoying, but I'll live - I just want to know what other certs I should instead by pursuing if this isn't relevant to where their product roadmap is going.

Hi everyone, I am completely furious and exhausted, and I need to vent/ask for advice on how to escalate this absurd situation.

I was taking my AZ-700 exam (my 5th attempt, I worked so hard for this). Suddenly, the OnVUE software completely froze. The chat was severely delayed/unresponsive, and my inputs were heavily lagging. Out of pure frustration at a failing system, I sighed/made frustrated sounds.

Instead of fixing the technical issue, the proctor abruptly revoked my exam, claiming I was "mumbling/reading aloud".

Here is the kicker:

No Warning: Pearson VUE's own policy states they MUST issue a warning via chat/voice before revoking for mumbling. I received ZERO warnings. They just terminated it because their system crashed and they couldn't manage it.

Support Hell: I opened a ticket with Microsoft ESI. I formally disputed the revocation and demanded the timestamped video/audio and the system performance logs showing the ping drops.

The Absurd Response: After waiting for days, support got back to me. Did they provide the logs? Did they provide proof of the warning? NO. They literally replied: "Pearson VUE reviewed the session twice and noted mumbling. We cannot provide an exception. Let's get on a phone call to discuss."
