App development final test — App development for students
The final test mixes questions from every lesson of the course: apps and users, ideas and features, wireframes, navigation and accessibility, data, events, if / else, loops, functions, debugging, test cases, permissions and version numbers. Pass it to earn the top badge of the course.
Plan, design, build, check — “use the right lesson’s rule for every question”
Find the topic: what apps are, designing apps, or logic and building.
Read every screen, list or code line carefully, top to bottom.
For code, write each value down step by step and check it again.
Use it for: Final revision before writing real app code in a programming course.
Worked example: 🐞 This code has a bug. What number SHOULD it show, if every line did what its comment says?
line 1: let lives = 34; // start at 33
line 2: lives = lives + 3; // add 3
line 3: lives = lives + 2; // add 2
line 4: lives = lives - 2; // take away 2
line 5: show(lives); // show it → 36
Follow the comments: start at 33, then 33 + 3 = 36, 36 + 2 = 38.
Work it out in your head or on paper, type the answer and press Check. Stuck? Press “Show me how”.
