I am a primary school teacher. At that time, I also entered the interview by preparing for the exam or something. Whether you need to write it on the blackboard depends on your luck. It is possible that the teacher you interviewed doesn't care about this. However, according to my experience, the writing ability of primary school teachers is very important. For example, if I write neatly, I will be criticized by the old teacher. In front of primary school students, I must write stroke by stroke and try to write orthography. In addition, generally speaking, as soon as you enter the class, people will ask you to write your name on the blackboard. The first is to know you, and the second is actually reading your blackboard writing secretly (that's what I did at that time), so I suggest you practice your name with chalk. What's more, you are preparing to give a lecture. It is possible that in the course of your lecture, the examiner suddenly suggested that now you are giving us a lecture. Take it easy. I immediately entered a state of high passion (I was like that). Finally, you said that your score was relatively low. If you can show your outstanding advantages to the examiner, I think your possibility will be greatly improved. Good luck. If you are not clear, you can continue to ask. Give it to me. Thank you.
