When you are a member of Paradoks, you get a discount on your study-books. Even better: the discount you get is way more then the cost of being a member for your complete studentlife! It is basicly a win win. To order books with a discount you need to be a member. So, if you are not a member yet, do not forget to become one!
Ordering books is possible here: https://paradoks.itdepartment.nl/. On the site you have to select that you are a senior student and then what module you are doing. Then the right books should appear on your screen.
If you have any questions about ordering your book you can contact email@example.com and ask your question.
