The application is made in the form of tests (30 tickets, 10 questions each). The application will help you prepare for obtaining permission to work independently on electrical safety over 1000 volts.

Menu sections:
- preparation - Each ticket contains 10 questions. All questions are in the same order. The correct answer stands out from the rest.

- training - Each ticket contains 10 questions. All questions are arranged in random order, so you won't be able to remember the answers just by their location. If the user makes a mistake in the answer, he will see the correct option.

- exam - When you select this section, 1 out of 30 tickets is randomly selected. This ticket mixes questions and answers to them, so you won’t be able to remember the answers just by their location. If the user makes a mistake in the answer, he will not see the correct option.

- marathon - When this section is selected, all 300 questions are shuffled and displayed to the user in random order.

Upon completion of each section, the test result is saved.
