I think I feel like I should change the answers on the study guide
For real? Why would you change the answers?
I don't want my friends to fail, I'll help them out by changing the answers on the study guide.
You shouldn't trick them that way. You need to just learn and study together and get the material down as a group.
No. I'm going to change the answers on the study guide.
That seems to be devious and very sneaky. Even if you think you are helping your friends you will get caught doing it. Then no one will benefit from it all.
