First, read the English article below.

You’ll obviously want to answer as many questions as possible without running out of time. In addition, knowing the right answers to the questions above and below a tricky true or false problem can help you find a pattern. Guessing based on a true or false pattern is better than just guessing randomly. When answering the questions that you know on a test that has a separate answer sheet, make sure that you skip the same questions on the answer sheet as you do on the test itself. This way, your answers won't become off set. Suppose you know the answers above and below a tricky question are both true. Chances are, the correct response to the tricky question is false. There is a low probability that the same correct response will appear three times in a row. Absolute modifiers are words that don’t allow for exceptions, such as all, everyone, never, and always. There aren’t many things that always happen without any exceptions, so questions that have absolutes are usually false. When a question with an absolute modifier is true, it’s often a well-known, common sense fact that doesn’t make for a good test question. In-between words, as opposed to absolutes, are more likely to be true. If a statement allows for exceptions, it’s more probable that it’s true at least some of the time. Other in-between words include usually, often, seldom, and frequently. Go with true if none of the other true/false tips apply, and you have no clue what the answer is. Recalling a fact is easier than inventing a falsehood, so test makers tend to include more true answers than false. For instance, if you’re stumped on a question with no absolute or in-between modifiers, and if the answer above is true and the one below is false, your best bet is to go with true. 

Now, please write a short abstract for it in Vietnamese. Abstract:
Bắt đầu trả lời những câu hỏi mà bạn biết đáp án. Chọn câu trả lời đối nghịch nếu các câu xung quanh đều có đáp án giống nhau. Chọn đáp án "sai" nếu trong câu xuất hiện từ mang nghĩa tuyệt đối. Chọn đáp án "đúng" nếu bạn thấy những từ như "một vài", "hầu hết" hoặc "một ít". Chọn "đúng" nếu bạn thật sự bí bách.
