Firstly, I would like to thank you for this resource. As an IB student in HL Physics, I have struggled with gaining a thorough understanding and mastery of this course, and have been hoping for a resource like this for the past couple of years. Now that I have found Paper Plainz, I am delighted to finally be able to reach my full potential. I have gained so much confidence just in time for my exam in a few weeks, and I am eternally grateful to the creators of this amazing resource!

PaperPlainz quite literally saved my IB Physics grade! The website is like the course syllabus with extreme detail in every topic, sub-topic, and sub-subtopic. I felt sure that I was covering every detail I needed to know for the exam and never felt like anything was missing. With the exception of past-papers (due to copyright reasons), PP is literally everything you need to study. It has got SO many practice questions, with detailed videos explaining even the most basic of concepts, which makes it so much easier to follow. It has even got video answers to all important past papers, which is incredibly helpful when checking exams you may do for revision. I cannot say this more explicitly, Paperplainz is the only thing you will need for your IB physics. You could do the entire IB physics syllabus without going to class and still get an amazing grade with PaperPlainz. (do go to class though, it’s worth it).

Paperplainz has been a very reliable resource in the two years I’ve been using it for both quick touch ups on my physics knowledge before a test as well as much more in depth revision for my mocks, as well as final IB exams. The explanation videos are very good at giving an understanding of the idea behind a topic, and then the practice questions are great for reinforcing the knowledge we learned from the videos and in class. Since there are a lot of IB (or at least IB-style) practice questions in the questionbank I was able to use PaperPlainz for a large mass of my final exam studying, which is wonderful since I was able to have a majority of all my physics studying material in one place.

Paperplainz has been an extremely helpful resource for me throughout the past 2 years of my IB physics course. It has an almost unbelievable amount of features, from good IB-focused concept explanations to help you understand topics (Showing you the stuff that will actually be on the exam), to endless revision resources like sub-topic quizzes, question bank topics by unit, past exam paper solutions, and even several mock papers to practice on. I think my favorite part is that over the 2 years the number of resources on the website has continued to grow. Not once have I thought “Wow, this website is missing this feature”. Overall, Paperplainz gave me confidence in my IB physics course as with it I felt like I could thoroughly understand any topic that I truly wanted, and it helped me do very well and develop a good understanding of Physics. Thank you Paperplainz!

I really love this website. Once I did not like physics at all, but the website is so interesting that it guides me to explore the beauty of physics. Thank you! 
Edit: With your help, I got a 7 in Physics and an overall score of 45 as my final IB score.

I have been using Paper Plainz since 2019 and found it invaluable as a new teacher of IBDP physics. The IB has a peculiar style of framing problems and the worked video solutions helped me get better, enabling me to help my students better. I have also appreciated how the site has evolved to also present concept explanations, quizzes, and revision summaries. Great work and keep the resources coming to help teachers get better at the technical to keep room for the socioemotional aspects of teaching. Thank you :)
