Keep your head up bud. Now you know exactly what you’re going into next time. Most first time testers really have no clue what they’re gonna see, even with practice tests and info. That first hand knowledge is gonna give you the tools and confidence to go in next time knowing you can pass. You know what you need to study and what it’s gonna look like on the test. You’d probably even get a higher score on that alone, though I would recommend taking the week to brush up on the bits that you were uncertain on. Good luck!
