UPDATE 2022: I am archiving all repositories that I don't use anymore or that have had no activity in the recent years. Therefore, this repository is being archived for these reasons.
These are some of the tests which I was able to find through some digging on the Internet and with the help of some other people. I cannot guarantee that all the answers are right since most of them are answered by me. Some files might have a TODO comment which specifies my insecurities about my answer. I also attached the exam as a PDF type for each folder. Only 2011 is attached as JPG images as the PDF was not found.
Now included on these collections are the Exam Tools shared by Maxim and the solutions shared by both Maxim and Niels. These are located inside each folder, in a folder called Solutions. Inside you will find the solution by each party.
An Index/"Table of Contents" is available at the first page by the name "Overview of all exams with their exercises" in both .txt, .docx and .PDF , provided by Isabel.
