As long as there is no scheduling conflict I don’t see why you wouldn’t wait until June (I assume you are applying next year) since even if you need to take it over, schools accept the Nov and Dec tests, and sometimes even the Jan test of next year. And like Midwest said, spacing it out will help it stick so take your time and don’t cram.
And a note about the essays…
They are not looking for the type of essays you do in school so just beware when you have someone look at your papers that they aren’t just looking for good writing but know what SAT graders look for too…
