I agree with Tailsfan101, since that's one of the most challenging aspects about the nationals tests. I would also practice outbreak scenarios because the entire test is like solving an outbreak that you're dealt with. Make sure you know how to APPLY your knowledge. The test has very little (if at all) reliance on memorization, but application is key.

The National DD tests tend to be quite long (~20 pages), so my advice is to split up the test, if that isn't already your strategy. They also tend to have one or two outbreak scenarios.
Yeah. I distinctly remember the test two years ago being around 36 pages. It's not so much concepts you study for; it's more about using logic.

I just wanted to confirm that this is the proper way to write a case description.

The time it happened (onset)
Place it happened.
Characteristics of people affected
Symptoms

Is there anything I have to add?

What's the difference between an experimental study and a cohort study? It seems so similar.

In an experimental study, you subject people to an exposure while in a cohort study, you find people who have already been subjected to an exposure. A cohort study is often used because it isn't ethical to introduce an exposure like sex or smoking cigarettes into an experimental group.

thank you
BTW, are there things like identifying parts of, say, a line listing, or what type of data or table it is?

I know that the rules for the next season aren't out but at least for this season, were their any instances where competitors had to apply Kaplan-Meier analysis to given data?

I sincerely doubt it, but I guess I'll let other people respond.

I did disease for two years and I don't know what that is.
