25 March 2021: A second HL Paper 3 mock exam (MockB) with worked solutions has been posted on the Sample Mock Exams page.
21 February 2021: The first HL Paper 3 mock exam (MockA) - with solutions - posted on the Sample Mock Exams page.
A full 'set' of Paper 1 and Paper 2 mock exams, HL and SL, are available on the Sample Mock Exams page.
** Please do not share mock exams from this site with anyone outside of your school's mathematics dept. Thank you.
With only one set of Specimen Papers - and no past exam papers - currently available for the new Analysis & Approaches course, some additional high-quality sample mock exams can be very useful for both teachers and students.
There is a strong argument that the most important assessments - other than the IB exams taken in May or November - are the mock exams (i.e. 'practice' exams) that students take 2 to 4 months before their IB exams.
There are essentially three ways to 'make' a mock exam. In order of difficulty - from least difficult to most difficult (in my opinion):
1. Use a full IB past exam.
2. Choose a selection of past IB exam questions from different years.
3. Write your own.
[or some combination of these approaches]
A subscription to this site offers a 4th option which may be the 'best' option - and that is using a sample mock exam written by me. It might be 'best' ... not because I have good skills and experience in contributing toward the writing of IB exams (which I do), but because there are significant weaknesses in the other three options listed above.
The biggest danger nowadays in using a full past IB exam question is that students have easy access over the internet to past IB exams going back many years. Thus, you may choose a past exam (one that you did not use with your students) as your mock exam without knowing that some, or all, of your students had obtained their own access to it (and the markscheme).
The same danger also applies to constructing a mock exam from a selection of past exam questions from different years. It is sometimes difficult to remember precisely which past exams you used with your students. It is also very difficult to organize questions from different years and get them to 'fit' together in a way which makes a good exam. It is not easy to get the right balance in terms of covering the breadth of the syllabus and arranging the questions in a suitable order from 'accessible' (i.e. easier) to 'discriminating' (i.e. harder) questions.
Writing your own mock exam can be a very worthwhile process. However, this is something rarely done by teachers because of the time and effort required. It also demands a certain depth of experience in teaching the course - and it would also be very beneficial to have had experience as a member of an IB exam writing team. And that's the last reason why it's very difficult to write a mock exam on your own - it's much better done by a team of people.
I have written a set of original mock exams (including worked solutions) for subscribers to this site. Although not a genuine 'team' effort, I did share these mock exams with other experienced IB teachers to check for suitability and accuracy.
