Complete filling technology
1. Before use, grind the nib on the paper into a horseshoe shape (about the same thickness as the small grid), which is more suitable for filling than the small grid.
2. You can choose to buy a special machine card reader to fill the mechanical pencil, because the tip of the pencil is already horseshoe-shaped.
You can choose to buy a ruler to make it up. There are holes of the same size on the ruler, just fill them in.
4. The form cannot be folded when filling in, otherwise it will be invalid.
5. When filling in the answer sheet, you can touch the wall or ground objects by hand to eliminate static electricity.
