Arent we making this all too complicated? Arent there more things to worry about than the pencil to be chosen? Any simple HB pencil would do, I borrowed couple from my son’s school box.
On this exam, go for 0.7mm. It fills in the ovals faster, and that’s what matters here.
For regular stuff, I do like the 0.5mm leads. Though these days I do almost everything electronic or in pen, so I’m working on memories here.
I hate .5MM lead because I always break it and sometimes it will cut through really thin paper.
Handwriting is definitely a lost art as everyone types almost everything. My cursive is so illegible so I had to write in print on the exams which is much slower but at least it is somewha legible. Now I can’t write in cursive anymore because I got so used to printing while I was studying for the exams. It makes me wonder if kids 20 years from now will even know how to hold a pencil.
