👩‍🏫Feedback

🔍️I can see you validate the menu input. When I press an option that doesn't exist it let's me try again. However there's no message saying the input was wrong. It just silently fails.

🔍️In ChooseSign(), signSelected is always false:

bool signSelected = false;

do
{
    ...
} while (signSelected == false);

The loop only terminates because a valid selection executes return. A simple while (true) would therefore better express what's happening and remove an unnecessary variable.

🔍I'd also consider replacing these parallel lists:

List<int> gameScores
List<TimeSpan> listOfTimes

with a GameResult model containing Score and TimeTaken. Parallel lists work here, but they depend on both lists always having matching indexes. A model would keep related information together and make it easy to add fields such as difficulty or operation later.

🧐Challenges Review

✅ Difficulty levels — Easy, medium, and hard alter the ranges used to generate questions.
✅ Timer — Stopwatch tracks completion time, which is also included in the game history.
✅ Random Game — A random operation is selected for every question.
➖ Number of questions — Not attempted; games currently contain a fixed 10 questions.

🗺️ Suggested next step

I noticed that you already complete our OOP course. I'd highly recommend taking our LINQ Fundamentals course next. LINQ is one of the most important tools in modern C# and becoming comfortable with it will make your code much cleaner and more expressive.

👪Oh and if possible join our Discord Community and add your username to your profile so you can be part of the community as well. 😁 And do you mind adding a country in your profile as well? The dashboard and leaderboard look neater when there's a flag. If you're not comfortable with that you can submit a random country.

☕If you like our roadmap, please consider buying us a coffee. We appreciate your help 🙂

Overall great work!✋🏻Looking forward to seeing your next projects!
