今天刚刚改的通知，具体怎样还不知道呢。以往没有计算机阅卷，都无所谓。Please use black ballpoint pen at all times; to complete your details on the booklet and when answering the exam questions. (Pencil, fountain pens, gel pens, roller ball pens, metallic effect pens, glitter pens and other colours of pen (including highlighter pens) will not be picked up by the scanning technology and could result in questions not being marked correctly.)——照这个意思，black ballpoint pen应该就是我们常说的水芯笔。roller ball pens,是圆珠笔。
