I did all by myself without viewing the youtube guide. (Except for the method in which i asked claude cause i didn't know how to do the timer thing).

@SamuelCabeza Project approved! 😄✅ Very cool implementation of the math game with the difficulty levels dictated by time to answer the questions. I don't think I've seen that approach, very original 😊

🥋And congratulations! You got your Green belt!! 🟢🟢

👩‍🏫Feedback

🔍️There is an important menu bug:

Console.WriteLine("6. Exit");

but GetDifficultyLevel() only accepts values from 1 through 5:

if (int.TryParse(input, out difficulty) &&
    (difficulty >= 1 && difficulty <= 5))

🔍One thing worth noting is your comment:

//Timer, this method was done by IA

Using AI assistance isn't inherently a problem, but make sure you can explain how Stopwatch, Console.KeyAvailable, Console.ReadKey(intercept: true), and the timeout loop work. That's where the learning value of using assisted code comes from.

🔍You repeatedly create Random instances. It's better to have one shared instance:

var random = new Random();

and reuse it throughout the application. Random.Shared is another simple modern option.

🔍Your timer calculation also works, but nested ternaries become difficult to read:

int timer = difficulty == 1 ? 60 :
            difficulty == 2 ? 30 :
            difficulty == 3 ? 10 : 5;

A switch expression would communicate the mapping more clearly:

int timer = difficulty switch
{
    1 => 60,
    2 => 30,
    3 => 10,
    4 => 5,
    _ => throw new ArgumentOutOfRangeException(nameof(difficulty))
};

🕵️‍♀️Also, have a look at our style guide since there are a few issues in your code. e.g. lots of unnecessary comments, as per picture below. You can read our code conventions here🤓.

🧐Challenges Review

You’ve actually extended the standard Math Game quite nicely.

✅The difficulty levels are a good addition, particularly because they have meaningful consequences rather than simply changing a label:

✅ The timer implementation is also a substantial extra feature. It handles character input, backspace, Enter, and timeout without leaving an unfinished asynchronous read hanging around.

✅ Your Expert/random game mode is another good extension. Randomizing the operation independently for every question makes that mode meaningfully different from the standard games.

🗺️ Suggested next step

I noticed that you haven't completed any of our courses yet. I suggest you try our Intro to Object Oriented Programming course next. This will close gaps in your knowledge and give you more confidence about OOP
