            foreach (char answer in useranswers)
            {
                if (char.ToUpper(answer) == char.ToUpper(CorrectAnswer[count]))
                {
                    rightanswer++;
                }
                else
                {
                    wronganswer++;
                }
                count++;
            }
            if (rightanswer >= 15)
            {
                Console.WriteLine("Passed with {0} correct answers! You are amazing!", 
                                rightanswer);
            }
            else
            {
                Console.WriteLine("Failed with {0} incorrect answers", wronganswer);
            }

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

The first thing you need to do is store a list of which questions he got wrong ... you don't do anything with that at present, so have a think about what collections you know how to use, and decide what you want to store them in.

Then use that inside the if block so you can print it later.

But... this is your homework, and we don't know what you have been taught s far, so I'll give you no code!

Give it a try, and see how far you get - this really isn't complicated if you think about it for a few minutes.

Because the part that show the list of incorrect answers is missing in your code.
1) you need to choose where to add the code for list of incorrect answers.
2) Just as you checked each answer to count correct and incorrect, you have to check them again and print the number of each incorrect ones.

C#

foreach (char answer in useranswers)

Advice: Never use a for each loop to scan 2 arrays, it only makes code harder to read and do not save the counter of the loop, you handle it by yourself manually.
In this case a for loop will make obvious that you are matching the same positions of both variables.
