I’m often getting queries related to the number of questions this site really have. It’s difficult to say since I add new questions and also delete duplicate / low quality questions in on going manner. To keep track of the total number of questions, I’m adding a counter on the right side bar. Every time I add or delete questions, the counter will be updated. I’ll also break up the total number of questions by knowledge area and provide it in the exam questions table very soon. This is not a very important feature.. but some people want to know more..
