Sir, I got half of my answers wrong as I put in the "i" after the number. Instead of the mark I should have gotten it was extremely low even though I had put the correct answers in. I took a screen shot for proof to show you tomorrow. Thank you Sir.

Sorry to be a plaque but I did terrible in that test thing and am wondering if I'm doing the questions wrong or if I'm not writing it correct but I didn't use i? The retest would be good now :L
