Maybe this will help some.

Having a "glass" of something is extremely vague. A "standard" pour is one thing. It could be 5 oz of wine, 1 oz of liquor, or whatever. I think the test writers are banking on the fact that people bring in the subtle assumption that the scientists are referring to the conception of what a standardized pour is (at least the one they use in U.S. I really don't know about anywhere else).

For example, if I introduce the idea that binge drinkers tend to drink the strongest alcohol % of wine they can find and fill the glass to the rim each time, and that's what they consider a glass, well that really changes things. And then perhaps the people who have 3 glasses a day are going to like a wine tasting where they give you like 2 or 3 oz. Maybe the scientists are from some organization or country that has a totally different standards and conceptions of what a standard serving is or should be.

I got a 151 diagnostic. I used Khan Academy when I did this test, and I did not do a blind review as they did not have the option to do this, but I could now as I never looked at the answers.

I could not finish the test in time, so I left many questions blank. It was rough and somewhat demoralizing! The time crunch is crazy. I think it's a good sign if your BR is higher, it means you get the concepts and have room to grow.

I will probably do a blind review for this test now, because your comment reminded me I could!

Diagnostic 151 / RC -6 / LR -9 / LG -13 / LR -15

P= /say bad

P' = /bad rep

C= possible to be good --> say bad (bad rep)'

These series of questions were not conducive to happiness. :(
