The intent is to provide useful information that resides on the outskirts of test prep, info that is not necessary to achieve a higher score, but that does enlighten.
Also, these posts will be better than first drafts. They will include properties that make for good essay writing on standardized tests: organization, helpful transitions, supporting examples, etc. Even though they won’t strictly mimic their format or purpose, they will subtly influence students by adding to their collective experience some examples of good writing.
As with any good writing, comments and critique (no, I’m not afraid of it because it makes me better) are welcome.
