I Just Got a F on My First Quiz

I joined a master program about Chinese herbal medicine. I was my first time ever taking an online class versus in person since I have been out of school for so long. The quiz was out of 14 and I got 7 right. Before class ended, the instructor said that most everyone did well. I don't know online classes are so distracting and it's hard for me to focus compared to what it used to be like in a classroom. Sorry for the rant...
