I’m not sure I’ve ever understood a topic less than I did before the lectures after the lectures until now. It would be great if you succinctly summarized the combined index and sort more effectively. An example would be pointing out that the index does not care about the order of the fields but sort does. I completely switched them.
It would also be nice if they disabled hitting enter to submit scores if at the same time they are going to auto-highlight the submit button. Sometimes easy of use results in accidental use. Glad I don’t have Parkinson’s or other motor skills issues or I could fail all of the labs accidentally.
