Has the case of cost engineer been put into the original question?
You can't bet on the original question now, it's illegal. In recent years, although many institutions have been selling bet topics, this book is based on teachers' past experience to draw some key points or find previous topics (which is extremely inaccurate), so it is generally based on materials rather than topics. Last year, I took three courses and bought the intensive materials of the exam 100, and the hit rate was about 80%, which is only the key point.
