Based on past exam experience, you can usually enter the designated exam room 30 minutes before the exam starts on the spot. For example, the exam will start at 9:00, and at 8:30, the exam will be taken on-site, and valid documents such as admission ticket and ID card will be verified. If you are 20 minutes later than the exam start time, you will not be allowed to enter. You will not be able to submit your papers until 30 minutes after the exam starts. If you fail to log in and confirm on the exam machine within 20 minutes of the start of the exam, you will be deemed to be absent from the exam. Therefore, if you are far from the examination room, you can go a day early to familiarize yourself with the environment. Most examinations are arranged in universities. There are many teaching buildings in universities and it is not easy to find.
