Should I be worried of being accused of cheating? So I just took a very simple, all-multiple choice test. I will straight up say I did not cheat, put bags phone etc across the room from where I sat, and the test was very easy. I marked all questions that I’m not sure of with an asterisk, and then when I went over the test papers, I wrote down the questions in the palm of my hand so I could check for answers immediately after handing in the test and getting out of the room. This is something I suddenly wanted to do so I know what I did wrong immediately and get a slightly clearer idea of how I did. I probably should’ve just asked the TA for an extra scrap of paper to make it transparent but I didn’t think of it at the time. I handed in the test and waved him goodbye. I’m not sure if he saw that stuff was written in my palm when I waved at him, but he just said like have a good one. Now that I think about it, this is far from cheating but probably an ambiguous move that might stir up misunderstandings. Just in case I took a picture of my palm with the contents to show that the contents are not like cheat reminders, just a list of the questions I didn’t feel confident about in the test so I could check them later, but still I’m worried that misunderstandings will crop up later and I will be swept into confrontations. Should I be concerned about my academia integrity standing?

Also it’s not an exam, not sure why the testing tag shows up like that. It’s a normal quiz.
I'm going to just guess here that there won't be any problem. If there were, you'd likely have been challenged when you left the room. I'll also guess that no one even noticed. 

You seem to have a decent sense of what is allowed. If you are challenged, just tell it like it happened and your thinking about what you did at the time. No one but your instructors can judge, but I think the issue is past you. Probably fine to just relax. 

But note, also, that none of my statements are definitive. Too hard to make firm statements from a distance.
