Failed CompTIA sec 701 TWICE!

So I took my second attempt today and got a 720. First attempt got a 697. I feel devastated because during the test I felt confident that I knew each answer! I did dion trainings course on udemy and also did professor messer and got notes and did several practice tests as well as made two sets of flash cards and studied my butt off. Not only for just test taking but I actually went through to understand each topic and how it all worked. I just don’t know what else to do. I feel so down. I know I won’t give up and I can take it again in 14 days. But I’m just feeling a bit discouraged tonight. Any tips on studying? Or test jitters? Not sure if my nerves were racing that made me not do as well.
