Several Wrong Answers

Attached are screenshots of the answers that I got wrong on the exam. You‘ll see that I received no points for each of those question. Secondly, there are some answers that I positively knew were right therefore I DID NOT change them based on the answer key I bought and luckily I didn’t change my initial answers because they were correct. So in actuality, there’s more than just a just few wrong answers on the answer key that I purchased.
