Are these questions ACCURATE?

I found these sample questions on the CFA website. Just wondering if they’re accurate representation of the difficulty level. http://www.cfainstitute.org/cfaprog/courseofstudy/pdf/SampleLevel1Qs.pdf I was doing some of the qs from the back of the CFA official curriculum and it seems a lot harder than those qs!

Those are a scam to get candidates to sign up. Classic bait and switch. Put easy qs on the website and switch them out with hard as hell questions on the exam.
