Dear Sir/Ma'am, I have completed three courses, but in the first quiz of course four, there is some problem. Even if I answer all the questions correctly, the results say that I have answered only three questions correctly. I tried refreshing the page again and again and also tried to do it with the incognito window but it also failed. Please help me.
Please make sure you are giving the correct answers, else try to clear the browser cache and solve the quiz again.
