On the whole there are no huge changes on the May Test. However, there are a few small tweaks …
Compared to the average of the 8 Official Tests, the May Test had
3 more punctuation questions - matching a growing importance placed on punctuation
2 less grammar (consistently of plural vs singular or verb tense)
2 vocab questions - matching the trend (whereas March had four!)
graphic questions remained constant at 2
zero organization questions (where you place a sentence in a particular part of the paragraph) - where most tests have anywhere from 1 -3
3 questions that ask you to keep or delete a sentence - where the May test had zero!
On the whole there were no great changes - but rather some minor shifts.
