Use the LawHub testing interface to practice at least once, that is exactly how it will look on test day.

It's never been something I can remember being tested on directly, however to answer your question I would absolutely say yes causation does imply correlation. If you already have a proven causal link, therefore the two things interact with each other in some meaningful way, its showing what a correlation is trying to imply. It doesn't imply how it correlates (positive, inverse, etc.) and with what metric we are measuring (a light switch causes a light to flip from on or off, but there's no correlation between the state of the light switch and the weight of the system), but there must be a correlation.
