Many people manage to draw fine graphs without equipment. I mean, they don't really care if it's a half-a-page da-Vinci, or a rough free-hand (expect for maybe the x and y-axis). Well, that's just my opinion.
As a side note, people general make the most mistakes at the beginnin' 5 to 10 minutes, possibly because of anxiety, which is why its recommended to at least always check question 1, and why people often chose to do Question 8 because they are Proofs, so mistakes are less unobvious, as such.
Btw, good luck to you Ext2 people out there.
