I used a gel pen in my English exams and then my friends told me I would be disqualified because all my work would smudge out when it's scanned, is that true? (Those were CIE exams)
I started using a ballpoint pen (one of those with 4 colours on them) to be safe but it's so much more uncomfortable and tiring because I need to use more pressure to actually get the ink to appear on the page / doesn't flow as well. I'm doing past papers at home using the gel pen and I really prefer it. I've got at least 8 pens in my ziploc (bought some cheap ones in a pack) though so at least I won't run out of ink.
