What IB Physics resources are available on PaperPlainz?

Concept Explanation Videos

Comprehensive, concise concept explanations, aligned with the new Physics syllabus that started in 2023 (first exams in 2025). We offer over 200 videos that cover all five major syllabus topics and also most concepts in the Mathematical Tools section of the Guide. The content here is designed to help you at every stage of your Physics learning.

Questionbank

A collection of exam-style questions arranged by Topics and Sub-topics. Paper 1A multiple choice questions are accompanied by full Video Solutions and Done Under 90 video explanations. Paper 1B and Paper 2 questions are accompanied by worked solutions and Video Solutions. (Note that we are in the process of adding Video Solutions and Done Under 90 video explanations to some of our questions!).

Past Exam Video Solutions

Well over 2000 clear, to-the-point video explanations of all SL and HL Paper 1, Paper 2, and Paper 3 (Section A) IB Physics past exam questions from May 2016 to May 2024. The new syllabus will first be examined in May 2025 and video explanations for the Specimen papers are on the way!

Sub-topic Quizzes

In this section of our Practice Exams you will find Sub-topic Quizzes with hundreds of exam-style questions arranged by syllabus topics and sub-topics. We created these quizzes to help you practice after learning new concepts and to revise before shorter class assessments that are focussed on one or a few sub-topics. Paper 1 questions are accompanied by full Video Solutions and Done Under 90 video explanations. Paper 2 questions are accompanied by worked solutions and Video Solutions.

PaperPlainz Accelerator

In this part of our Practice Exams you will find the PaperPlainz Accelerator – ten sets of mixed, exam-style practice questions that contain Paper 1A and Paper 2 problems, arranged in ascending order of difficulty from Level 1 up to Level 10. We built the Accelerator so that you can start your mock or final exam revision with the basics and gradually turn up the challenge level as you improve. 

Mock Exams

In this section of our Practice Exams you will find full-length IB-style Mock Exams that include questions from all topics and are based on the format, content, and difficulty level of the real exams. Here we offer eight full Paper 1A, Paper 1B, and Paper 2 exams for both SL and HL. As always, Paper 1 multiple choice questions are accompanied by full Video Solutions and Done Under 90 video explanations. Paper 2 questions are accompanied by worked solutions and Video Solutions.

IA Guide

A complete, step-by-step video guide to help you save time and achieve the grade you want on your Physics Internal Assessment. From start to finish, these videos walk you through all key points and details of how to write a high-scoring IA, offering videos, specific tips, examples, checklists, and questions that you can ask when discussing your work with your teacher.

Step-by-step Internal Assessment Guide

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.

IBDP Student, China, May 2022 Exam Session

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 :)
