I’m so frustrated with the Network Security Essentials exam

How is it that for every practice test I find I can score a 90% but on the actually exam I get a 72%?? I am literally 1 or 2 questions from finishing this bs exam and I can’t seem to get it. I went through the study guide and videos multiple times so I honestly don’t know what to do anymore. I passed the Network+ and A+ in one try with a near perfect score but this is the first time for any exam where I’ve felt like the answer could be multiple depending on how they mean to ask the question. I cant keep failing this shit man. Any advice?
