Can you use a number 3 pencil on a Scantron?

It turns out, black ink isn’t opaque enough for these old scantron systems. Further, lighter shades of graphite, such as in #3 and #4 pencils, weren’t sufficiently opaque enough for these old systems to perform without error, as is generally required.Click to see full answer. Also to know is, what happens if you use a number 3 pencil on the SAT?Using a number 3 pencil probably won’t cause any problems for you.Also Know, what is a number 3 pencil? Pencil makers manufacture No. 1, 2, 2.5, 3, and 4 pencils—and sometimes other intermediate numbers. The higher the number, the harder the core and lighter the markings. (No. 1 pencils produce darker markings, which are sometimes preferred by people working in publishing.) Simply so, what happens if you don’t use a number 2 pencil on a Scantron? The pencil lead weight that corresponds to #2 pencil lead is “HB.” With the same type of lead, it’s deeply unlikely any scantron machine in use today, no matter how outdated, would have trouble reading your markings. (You can read more about lead grades and mechanical pencils here if you are interested.)Can you use a 2.5 pencil on a Scantron?You’ll most likely be just fine. Scantron machines used to only be able to read the graphite in pencils (#2 being the optimal one for writing. This is useful in art and stuff, but 2 is a standard for schooling), but most current Scantron machines just differentiate between color and blank papers.
