### 3/5 — Has incorrect answers

*2022-06-06, version 0.1.1*

One question asks for the “highest” best case scenario for sorting: quicksort, selection sort  merge sort, and bubble sort. It says the right answer is quick sort, and correctly identifies quicksort as having a best case of O(nlogn)… which is far worse than O(n) for bubble sort. But if they meant higher as in worse, then it’s still wrong as selection sort has a best case of O(n^2), which is far worse.

### 3/5 — Helpful but has bugs

*2019-06-27, version 0.1.1*

Needs more debugging, especially for questions in which the answer is two of the choices (eg. choice 1 and choice 2; but it seems the are also randomizing the order so choice 1 and choice 2 do not correlate correctly)
