Registration handbook of UMPTN mentions that registration form and answer sheet will be processed by computer. It means that registration form and answer sheet will be scanned by optical mark readers that is connected to computer system. Pencil with 2B texture is the only toll that can be used to fulfill the forms. Another kind of tools will cause forms can not be processed. Meanwhile there are producers that promote a special pencil for computer. This cause confusion for many students. Furthermore, it might interfere their concentration in examinations. For student who lives in metropolitan this may not be a problem at all. But there become a problem for student who lives in remote region, since it is not easy to get that kind of pencil in remote region. It seems that computer discriminates against student from remote region.The result of this study shows that all pencils will give a good result if it is done properly. Improper fulfillment or careless handling of the forms will give an improrer result for HB pencil or harder and for 4B pencil or softer. While B pencils and 3B pencils still give as good result as 2B pencils. This study also discovered that brand of the pencils still give as good result as 2B pencils. This study also discovered that brand of the pencil does not influence the scanning process. Scanning result only depend on the texture of pencil, not on the brand and that there is no special pencil for computer.
