Ib Physics Past Paper Solutions
Fernando Capelle
Our recommendation is that you prepare for the coming open book exams in a similar way to what has been successful for you in past exams. This time round you know that you have the fallback of referring to your notes if you need to, but for the benefit of your future studies as well as these exams you want to be as familiar with the module material as you can be. Your coming exams are still time-limited, so you are not likely to have lots of time to refer to your notes.
The coming AS and PH exams will look reasonably similar to "usual", but it is likely that there will be less in there than in previous exams that requires a student just to copy a definition or a "standard" derivation from their notes. You can expect there to be marks that require a good functional understanding of the content in the module and associated skills.
We suggest aiming for a good functional understanding of the material in the module, as usual. That will likely be of great help for those of you studying with us again next session, and will likely be useful for you in the online exam.
We suggest that in preparation for the exam you generate a two or three page summary of core ideas in each module and how they inter-relate, and maybe relate to work in prior or concurrent modules. This will likely be useful in "seeing the wood for the trees", getting a better functional understanding, in seeing how things link together, and for quick access during the exam.
We recommend not spending substantial time re-listening to lecture-recordings for revision: you will likely gain much more from actively working with the material. If you can not make sense of something in the recording, there is probably a gap in your knowledge or understanding that is not in the recording itself, so that it is likely to be much more useful to consult other resources such as textbooks and your notes from earlier lectures, or discuss with peers, etc.
Once you feel that you are on top of the ideas and techniques in a module, or a chunk of a module, we recommend that you then get practice in problem solving from tutorial questions, past exam papers, and maybe exercises and questions in text books.
We note that past exam questions can be useful to practice, but these should not direct your revision. It could be that the August exam questions cover material that has not featured in the exam for that module in recent years.
The University publishes past exam papers for AS and PH modules; these are accessible from MySaint, Academic Activities.
The School of Physics and Astronomy publishes for most of its modules one past exam paper with a draft solution and often the generic feedback supplied to that set of candidates. This may be accessed from the School's home page > Current Students > Undergraduates > School information> Examinations - Past Paper solutions.
As agreed by the Teaching Committee, the department rule is to publish, at any point, the summer exam papers for the last 10 years. The solutions are published every three years and only three sets of solutions willl be made available.
The papers provided here are up to date as of the relevant examination that candidates sat in April/May/June. If any corrections were made to the paper during the examination, where possible the corrected paper is provided. If later revisions of the examination papers are received, the date of upload will be noted next to the relevant paper.
These model answers are provided as a guide to students as to what is expected in a good solution to an examination question. Due to the process by which they have been compiled it is unavoidable that there will be a few cases for which the model answer given here does not match the question asked in the final form of the examination paper.
By their nature, they can look quite challenging at the start of the year. The only route to success is practice, practice, practice. To help you on your way, we have compiled an archive of recent Comprehensive Papers for you to try for yourself. Some papers have model solutions so you can see the style and detail of solution expected.
In terms of the length of the questions, questions in paper 2 will be of similar length to the questions in the archive of Comprehensive papers. Questions in paper 1 will be typically shorter than in the archived papers. In order to reflect this difference, questions are marked out of 20 marks in paper 1 and out of 30 marks in paper 2.
There are two Year 3 core modules, Solid State Physics and Nuclear & Particle Physics. The examiners do not expect detailed knowledge of these two courses. However, it should be noted that some basic concepts in these area are covered in other courses.
Examples:
The Summer Examinations Timetable is created every year based on the year 3 & 4 options selected by students. The Year 1 & 2 exams are usually fixed but still subject to changes. The Exams Timetabling Policy is considered when creating the timetable.
We expect to publish the provisional timetable by November each year. The finalised timetable, whch includes the location, is usually published at the end of term 2. The finalised timetable should include the main location for each exam. Candidates who have confirmed Additional Exam Arrangement provisions and have been assigned an individual room will be contacted via email to confirm their examination venues.
Most examination enquiries can be answered using the materials on the Physics webpages, however, if you have further questions please see the list of contacts below:
General examinations enquiries should be directed to the Examinations and Information Officer, Victor Urubusi
Over the three years of my BSc at UCL I have accumulated awealth of probeme sheets and foremost handwritten solutionof past exams. I have put it all here for you.All of the solutions are a product of what my friendsand me managed to do in preperation of exams. A very special thanks and credit to my dear friends and study group: Camilla Tacconis, Lodovico Scarpa and Maksymilian Słupski. You made it worthwile.
All problem sheets, PSTs, ICAs and my handwritten solutions are available on below Google Drive for free.My Exam solutions are available for the price of a coffee via the links in the drive on my Stuvia account. This keeps the page running and me motivated to keep it maintained.
Just browse the drive and you will find the solutions in the respective folders.
We upload past test papers and reports on test outcomes as they become available to help prospective students prepare for the PAT. Note that the PAT has evolved over time and that past papers dated before May 2006 are based on an earlier syllabus and are not relevant to the current test.
We do not generally provide solutions to the past papers; when marking the PAT, all suitable methods for solving the questions are allowed and we would not want you to feel only one specific way of solving the problem will gain you marks. We have however published sample solutions to the 2009 and 2010 papers and our Access team has created unofficial sample solutions for the 2019 paper; these can all be found below.
The copyright in all the past exam papers made available here belongs to the University of Bath. You must therefore obtain permission before copying, redistributing or publishing all or part of any paper.
There is not necessarily a best way to use the A level physics past papers but it is good advice to use them sparingly as they are a scarce and valuable resource. Using the exam papers to monitor the progress of revision and to identify gaps is always useful.

Students can find the Karnataka-CET(KCET) 2020 Physics question paper with solutions here. With detailed solutions solved by our subject matter experts, students will be able to quickly understand the solution approach and identify the quickest way to solve the problems. The page can be used to directly view problems and solutions. This question paper provided on this page is downloadable in PDF format and is also available for offline viewing at a later stage.
Candidates can make more productive use of their time by referring to the solutions on this page whenever required, for cracking some of the seemingly difficult problems. Candidates can gain more confidence by practising the KCET 2020 Physics Question Paper and boost their preparation for the entrance examination.
