I have just downloaded the instruction file for the new Topik exam from the official Topik website
I’m very surprised to see that they have changed the OMR pen used for the Topik. In fact, they have changed the OMR pen since the 34th topik exam. The old OMR pen used for the topik is the pen with the thick and big nib as you can see in the photo. You will be provided this OMR pen to mark the answer sheets. However, the OMR pen with the thick nib will slow down the speed of writing, so I only used the OMR pen to mark for the multiple-choice questions and used the ballpoint pen for the essay. However, I heard that if we used ballpoint pens or pencils in the Topik exam, we would get minus marks in the essay.
But now , the new OMR pen has two nibs which are the thick one and the fine one. As you can see from the photo, the thick nib is used for the multiple-choice questions while the fine nib is used for the writing parts. I am really satisfied with this new change. Thanks for the new OMR pen, we can mark the answers and write Korean essays easier.
