Science test results so far

In three classes, 47 students wrote the test.  Here is the data so far

Mean 17.5/21 (83.3%, A-, well done)
Median 19/21
Range (4/21 to 21/21)

Please, read those pages if you want to do well. Use it during the test since it is an open book test.  There is no time limit!

If the book is left in school, use the online textbook access.

I will post another science test in two weeks.
