KnowR0 Reviews 

I didn't think buying additional study materials was necessary for the R0 exams. But after purchasing the R04 materials, I decided to keep purchasing them for the other modules. The content provides all the key information that is needed for you to pass the exam. The CII study text, although comprehensive, it is not easy to tell what you need to learn that is exam specific. I love the fact that their material does this.

I've decided not to purchase any of the CII materials (except for the study text and exam entry) because all their content is not helpful for the exams ie revision mate, audio learning, e-learning etc.

I have used KnowR0’s E learning and mock packages for R02,3,4 and have achieved over 84% on each exam first time, I couldn’t recommend enough especially if your someone who finds scrolling through 400 pages of work boring! It breaks down all the necessary information and provides lots of Qs to practice from

The most important learning materials I've used for R0 exams. I used the R01 and R05 mock exams first and have progressed with R02/R03 (and will be purchasing R04) e-learning packages. The materials are pragmatic, exam-focused and break down concepts into real-world examples and visuals that make sense. The mock exams and runthrough of the exam guides have been invaluable - I would not have passed the exams so far without these! Highly recommend to support your learning in preparation for exams.

The best learning resource I used. Used it for R01 - R05 for their mocks, and used their e learn for R03 and R04. I got 85%+ in all my R0 exams and I owe it all to KnowR0, what I found really helpful was the context menu, which gives real world examples on whatever it is you’re discussing which makes it so much easier to understand. It’s also one of the cheaper resources out there.

I can honestly say that this company is materials are absolutely fantastic they have a visual guide would which explains taxation for the ciiro3 module which is phenomenal and their question preparation as well as their explanation in detail as to how they get the answers to their questions in preparation for the exam was again absolutely phenomenal I cannot express enough how much I highly recommend there materials I have tried other providers which were good but this company is materials are just at another level i would highly recommend all their materials I say this without prejudice I have no attachment to the company

I could not recommend using KnowR0 enough to anyone looking to take their R0 exams!

I have used their material to pass 2 exams first time and about to sit the third.

Their exams mirror the real exam questions closely and their breakdown of why each answer is correct was essential in my preparation!

The KnowR0 material is brilliant for understanding the knowledge required for the Cii exams.

I used the R01 and R05 mock exams to help pass those exams.

Currently working through R02,R03,R04 e-learning packages which are hilarious and well as informative.

The KnowR0 platform is truly brilliant, it's perfect for my style of learning. I was able to do continuous mock exams in preparation rather than just having the book. I passed all of my exams 1st time with ease thanks to the KnowR0 platform and Jeff's study sessions. Highly recommend!

Once again, I definitely would recommend using the knowR0 mock exam resources for R02. These have continued to play a key role in my exam preparation and have proven effective in helping me succeed!
I have also previously used these resources for R03, R04 and R05! ⭐️⭐️⭐️⭐️⭐️

Some of the best material around to help pass my R0 exams not to mention the prices are reasonable. The context is easy to understand and digest. Would recommend for anyone who wants to pass first time round.

I have been using knowR0 in preparation of the R02 exam for much of 2025. It has been invaluable to me in helping me learn and understand. The syllabus is broken down into understandable chunks with examples and exam questions along the way. The mocks are very realistic and the explanations of the correct answers help you to understand further. It's also very cost effective. So forget all the alternatives on the market and consider KnowR0 to help you pass the R02 exam (and the other exams).

Amazing mocks, first time using it and got great results with the R02. Will definitely recommend anyone to give it a go. Great price too.

KnowR0 has been completely invaluable so far in my studies. It is user friendly and breaks down complicated topics in an easy to understand way. Went into my exam feeling confident thanks to KnowR0.

I just finished my training with Jeff for my RO exams 1-5 , and I can't recommend him enough! I passed them all 1st go.
The learning materials he provided were fantastic—super clear and easy to follow.
The mock exams were spot on, really similar to the real thing, and the explanations helped me understand where I went wrong. It made a huge difference in my prep!

Jeff’s webinars were awesome too. He was well-prepared and kept things fun with his great sense of humor, which made the whole experience enjoyable.
If you're looking for a trainer who genuinely cares about your success and knows how to make learning fun, Jeff is the one to go with

I've had an excellent experience with KnowR0 and highly recommend them to anyone about to embark upon their R0 exams. The content for each exam and module is broken down into much more user-friendly and understandable terms and I genuinely wouldn't have been able to pass without the mocks, the explanations and the support from Jeff.

If you are studying for the CII R0 exams then look no further than KnowR0. The content is clear, easy to understand and makes a very dry subject humorous and memorable. Their customer support is outstanding- I messaged late at night on a Friday, expecting a reply the following week, but instead it came through in a matter of minutes. The questions that you may have from reading the CII textbook are answered by their context examples. This turns the subject matter into real life situations that helps to see the logic behind the details you are trying to memorise. I've tried other brands before but this one is my go-to from now on. Wouldn't hesitate to recommend to everyone sitting these exams.
