The national high school mathematics competition is generally held on the same day and in the same place in the morning. At 8 o'clock, I got 12.

Taking the exam for 2 hours is a little more difficult than the college entrance examination, and the score is *** 150.

There is a 30-minute break, and then try again.

The duration of the second exam is 1 hour 30 minutes,1* * 3 questions, 150 points, with 50 points for each question. The first one is plane geometry, and all three problems are difficult.
