Depends on the reader of the test. I was told for my tests at my school that I had to use a number 2. However, 2.5 would likely work, but I wouldn't take the chance. By the way, I use the scantron for my tests.
A standard number 2 pencil typically measures 7.5 inches in length when unsharpened. The diameter of the pencil is generally around 0.3 inches. This size is commonly used for standardized tests and general writing purposes.
Instead of writing my essays in paper and pencil and ca type them and print them out. It has made me more lazy.

With a pencil
It is the traditional form of maintaining a business's financial accounts and records using a pen/ pencil and paper instead of using a computer spreadsheet.
Using an HB 2 pencil for standardized tests is beneficial because it produces clear and easily readable marks that can be quickly and accurately scanned by grading machines. The lead hardness of an HB 2 pencil is ideal for filling in bubbles on answer sheets without smudging or smearing, ensuring that your answers are accurately recorded.

It means that a number without any units is meaningless.For example, when you measure the length of your pencil, include units in your answer. It's wrong to say your pencil is 10. Ten what? That's a naked number.Say that the length of your pencil is 10 cm (centimeters) instead.
the function of a pencil is to write with out getting your hands dirty and to be able to write on paper instead of stone.
