New: the ABC and DT categories. The police's new question sets are separate: ABC (1050 questions) and DT (1380 questions). The category is chosen on first launch and can be changed in the settings. Tips: the first time each section is opened, the app walks through its controls step by step. They can be shown again from the settings. Explanations for nearly every question, in three languages.

New: Russian and English. The flag on the home screen switches both the app's language and the question bank — the official Russian (1031 questions) and English (1012 questions) sets, with explanations. Statistics and mistakes are kept separately per language. The explanation panel now opens straight onto its text, each practice mode carries its description under its name, and 34 cut-off explanations were completed.

The first five explanations are now free. Every question's explanation button shows how many free explanations are left, up to three a day. Ones you have already read stay open, and reopening them never costs anything.

New: question explanations. Every question now has an Explanation button that opens the reasoning behind the correct answer, with the sign and rule numbers. For the whole question base, bundled with the app and working offline. Explanations are part of the subscription. The free version includes 6 exam tickets a day and the mistake review of 3 of them. Everything else is unchanged: the whole question base, every study mode, the statistics and the accumulated mistakes list.
