In which, there are 4 true/false questions, each question has 4 ideas. Candidates who choose exactly one idea in a question will get 0.1 point; two ideas will get 0.25; three ideas will get 0.5. If they get all four ideas right, they will get 1 full point. Compared to previous years, the way of calculating points has changed, no longer dividing 0.25 equally for each question.
