Your language preferences are set when you start the test, not during the purchase.
When you purchase practice questions, you're buying a set number of questions from our database, not specific questions. This allows you to select the language for your practice tests in the "Start New Test" section.
Tip: Click the blue question mark next to each question type to see the number of available questions per language. This will help you make the right purchase for your needs.
