Based on the labs I've done, and other materials, I'd say it's NOT a "cheat sheet" exam.
It's really sorting out syntax and structures that fries my brain. Code never "sticks" with me, and I'm in a constant state of bootstrapping, for lack of a better term.
Are you taking the cert to get a job or is your job making you get the cert?
Getting your employer to pay for training and the actual cert is definitely the way to go. I have always discouraged anyone looking to get the cert first
There's a lot to the exam I get, simply from experience. I'm getting slaughtered on the Azure CLI stuff since I simply cannot get the syntax to stick, no matter how many times I re-run through the labs.
Do you feel you're not getting it or that you're not getting it fast enough? The latter can evolve into the former. And perpetuate the anxiety loop.
