The exam is written against syllabus paragraphs, so that is how the questions are organised. Every question carries its syllabus reference, so a drill, a mistake and your progress all point at the same chapter.
18 chapters · 1,266 questions
Sample chapter scores. See every module's syllabus
10, 20 or 30 questions from one syllabus chapter, or a set of chapters you pick. A drill records no quiz result, so a bad run never dents your module average.
Each question explains the right answer the moment you choose. Your mistakes go to Weak Areas, so they come back until you get them right.
Timed mock exams with the number of questions and the time limit of the real exam for your licence category: A, B1, B2, B2L or B3.
The Progress Center ranks your weakest chapters, tracks readiness per module and counts down to your exam dates.
It reads every answer you give and ranks your weakest syllabus chapters by how sure the evidence is, so eight answers at 50% outrank one unlucky question.
