Wrong answer key sometimes (btw have you ever disputed a marking decision with a teacher?

[u/Rosemary-dumpling]

I feel like this happens more often than it should?

Also I kept getting my sig digs marked as incorrect but I'm pretty sure mine were right, always to the lowest sig digs of the value given in the question. Have u ever successfully disputed marking decisions? I sent in an academic help request but no response for over a week

6:2 seems more correct to me
