A formative test helps you assess your progress in the course, and helps you address any blind spots in your understanding of the material.
If you get a question wrong, you will receive a hint on how to improve your understanding of the material.

Complete the formative test ideally *after* you've seen the lecture, but *before* the lecture meeting in which we can discuss any topics that need more attention.

```{r results = "asis", echo = FALSE}
source("formative.R")
questionnaire("formative2.csv")
