What is the point of going through all the Series III videos and the questions are nowhere related to what was discussed.
It is really frustrating because I am unable to solve the questions despite watching the videos to understand and Greg is not explaining his approach clearly.
Disappointed
@Leaderboard can you evaluate if the difficulty of this question is appropriate?
With the note that quizzes on PrepSwift are cumulative, this question is within scope. It did end up being harder than expected (acceptance rate as of writing is about 28.3%), but there is nothing to call this “out of scope”. That does not imply that there isn’t room for improvement in the solutions to these quizzes. My advice for you is to post the issue you’re running into as clearly as possible, so that we can help you and perhaps (if this is an issue we’re seeing with other students as well) update the solution accordingly.
Also keep in mind that it’s OK not to get every question correct - while most of the questions are meant to be accessible, some of the questions on PrepSwift are indeed meant to be relatively challenging and discriminate amongst the more able students. You can see the average for each quiz on PrepSwift - Because who has time?.
