2 pencils are needed for standardized tests that use Scantron sheets. Harder pencils may smudge easier and be harder to erase, while lighter pencils may leave lighter marks that the machine has trouble reading. Use a No. 2 pencil just to be on the safe side.
Do Scantrons really need #2 pencils?
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 With the same type of lead, it’s deeply unlikely any scantron machine in use today, no matter how outdated, would have trouble reading your markings.
Why do schools use number 2 pencils?
Pencils numbered higher than 2 have harder leads and are often used by engineers, architects, and draftsmen because of their harder points. The underlying logic here is that the harder point gives the user greater control of the lead.
What pencils work on scantrons?
#1 pencils would have worked fine, as they are darker than #2 pencils. But, unfortunately, they also smudge easier when erased or accidentally rubbed with your hand as you mark the scantron form, increasing the possibility of a “false positive” when the scantron was reading your form.
Do Sharpies work on scantrons?
Students should use caution when filling in their Scantrons; while it may be tempting to use Sharpies and to mark bubbles with x’s, there is always a chance that the machine could reject it. “It may go through, it may work, but it’s best for the students to use pencil,” Ousmanou said.
Do mechanical pencils use #2 lead?
Many mechanical pencils don’t include any kind of identification. However, even those mechanical pencils that claim to use No. 2 arrive in those very thin, easily breakable cylinder shapes.
Is No 2 pencil same as 2B?
A No. 2 Pencil in the US is the same as a HB pencil in the rest of the world. 2B is darker, which would make erasing wrong answers difficult.
Are Bic mechanical pencils number 2?
Mechanical pencils deliver a write-out equivalent to 2-1/2 wood-case pencils. Always ready, sharp and accurate, these No. 2 mechanical pencils are the smart choice at test time. Smooth-writing, break-resistant lead does not smudge and erases cleanly.
Which pencil is best for writing?

Upgrade pick. Palomino Blackwing 602. The Cadillac of pencils. Also great. Faber-Castell Grip Graphite EcoPencils with Eraser.
Why is it called a No 2 pencil?
Well, it all has to do with the HB graphite grading scale used to classify the pencil’s graphite core. The hardness of the graphite core is often marked on the pencil — look for a number (such as “2” “2-1/2” or “3”) — and the higher the number, the harder the writing core and the lighter the mark left on the paper.
Is a No 2 pencil the same as HB?
Generally, a #2 pencil is about the equivalent of an HB pencil. According to this system, pencils are graded on a continuum for “H” (hardness) and “B” (blackness), with a number to say how hard or how black it is. The more H’s you have, the harder the lead and the lighter the lines.
Who created the #2 pencil?
Henry David Thoreau and his father substituted clay for wax and created the world’s first #2 pencils.
What pencils are not number 2?
1 pencils, HB = No. 2, F = No. 2½, H = No. 3, and 2H = No.
What color is a number two pencil?
As it turns out, there’s actually some fascinating history behind the signature yellow color of No. 2 pencils. “During the 1800s, the best graphite in the world came from China.
Why are mechanical pencils better?
The great thing about mechanical pencils is that they stay the same length, making it easier to get a consistent grip and promoting good writing habits. The erasers on regular pencils are generally bigger than those on mechanical pencils, but not by much.
What is HB pencil?
The degree of hardness of a pencil is printed on the pencil. These pencils are soft. H stands for “hard”. HB stands for “hard black”, which means “medium hard”. F stands for “firm”.
Are Scantrons still used?
He said most teachers have generally stopped using scantrons, but are starting to turn to a new method of test assessment. “Most of the teachers don’t use scantron machines anymore. A lot of them are using Mastery Manager now and are using that system vs. scantrons,” Shaughnessy said.
Can I use a 2B pencil on a scantron?
Can one use an 2B pencil on an U.S. scantron? I have used 2B in America. No problems but I wouldn’t recommend it just because you are asking for less problems if you don’t.
What is the best lead size for writing?
Writing. If you’re going to be writing with your pencil, you’ll want lead thick enough that it won’t break too easily. With modern leads, 0.5mm is quite strong enough for most people, but more heavy-handed people do sometimes find they snap such thin leads, and 0.7mm or even 0.9mm leads are better for them.
Can graphite make you sick?
Graphite is relatively nonpoisonous. There may be no symptoms. If symptoms do occur, they may include stomachache and vomiting, which could be from a bowel obstruction (blockage).
What size of mechanical pencil is best for writing?
0.7mm is the most common lead size used for mechanical pencils. The writing style matches closely to the size of a fine ballpoint or rollerball, and is available in the widest array of hardnesses. The lead thickness is great for day to day writing, sketching and can be used for less detailed technical drawings.
Is a number 2 pencil graphite?
A No. 2 pencil is towards the middle when it comes to the hardness of lead (graphite) and the darkness of the shade. If a pencil has a number higher than 2 it means it has a harder graphite core, a harder point, and a lighter shade. These pencils are often used by engineers or architects.
What pencil is best for SAT?
SAT: Use a No. 2 pencil and a soft eraser. Do not use a pen or mechanical pencil.
What is the hardest grade of pencil?
What do the numbers mean? The H pencil range: The 9H pencil is the hardest and H pencil is the softest. The B pencil range: The 9B pencil is the softest, and the B pencil is the hardest.
