Hi,
Take a deep breath. This is the time to get your head in the zone. I'm a big fan of the review cram (I always scheduled afternoon exams).
I'm reposting the "test taking" portion of my overall post in the general section, here. One thing I've learned since then is that the cut scores are between 57 percent and 68 percent. NCARB shared this a long time back, but it's useful, because using flagging, you can gauge whether you think you'll pass while testing.
https://www.ncarb.org/blog/are-50-what-score-do-you-need-pass5. Test taking: First, answer every question. Use flags if you're feeling less than about 80% sure on an answer, but move on. Race through. Having time to review your answers will give you a lot of security. You can also get a feel for how you are doing.
Use the strikethrough tool. It's set up in a terrible and annoying way, but it saves you some mental energy if you don't have to look at a bad answer.
There is an awesome search tool in the bottom left of the case study materials. It can find room numbers and window tags and just about anything else! I didn't know about it until my last exam.
