I wouldnt worry about it man. The stress of the test is enough to make many people screw up. I am a prime example of that. Whenever I stopped worrying about increasing my score and actually went to take the test for real, I did well. You can pull that score up as much as you want, it just depends on how much time you're willing to put in it. Many of my friends and I boosted ours over 20 points just by using a study guide. If you have used a study guide, just go over where your weak areas are. If that doesnt help... remember as many questions on the test as you can and hope they are on the next one... That definitely worked for me... I honestly remembered over 100 q's and i will just say it helped really well 😎
Dont sweat it... you'll be fine man... just use your head and stay focused
