I work in education and I am a firm believer that all test should be open book. When I am in the real world and I don't understand something I Google it. That's an essential skill these days. Why not teach kids how to effectively find and use reliable sources on the Internet instead of having them waste their time memorizing stuff they won't care about or need five years from now.
Yeah it definitely needs to be reworked, let them use Google and make the questions in ways where you need to figure out the answer like using a calculator in math exams but instead with books and Google.
For sure, I would even make there be some red herrings in there.
100%! Give the right resources and let the student figure it out.
How to use google should be a class! Not everybody knows how to search....
I'd be out of a job if they did!
