1. Opening acivity

Here user decides if he wants to learn, test himself/herself or simulate exam.

2. Choosing subject

There is a list of subjetcs, so it enables user to choose questions of one particular subject. However, in learn mode and in test mode there is also an option to choose all subjects - and get questions from all subjects at once. In exam mode this functionality wouldn't make any sense.

3. Learn mode

Question is exposed with one, correct answer. By entering number in edittext and presing "Go!" button user can jump to specified question immediately. If there isn't any number toast will appear with message to enter number firstly; if entered number is out of range there also will be a toast - it won't crash app.

4. Test mode

Question is exposed with 4 answers (only 1 correct). When user taps answer it changes color to red (if it's wrong) or green (if it's correct). Answers are shuffled every time user goes to next/previous question or closes app. This forces to learn correct answer instead of correct order 😄. There is option to jump to specified question - same as in learn mode.

5. Exam simulation mode

Few random questions from subject are picked with 4 answers. Number of questions is same as on real exam in Civil Aviation Department. When user taps answer it changes color to blue. User can pick only one answer, but it is possible to change it - other will appear with blue background, previous answer will change background to default. Answers are remembered so user can go back to questions which he has already given answer to and change them. By pressing "check" button user goes to results view.

6. Exam results view

Here are displayed user's results from exam. There is a number of correct answers and also a percentage (correct answers divided by total number of questions). If score is above 75% (needed to pass exam) text is in green color with huge "Bravo!" on screen. Otherwise text is in red color, telling to try again.
