I’ve received a couple of inquiries about the updated AP English Lang/Comp exam, so I’m putting this out there now: yes, I am aware that the test is being updated for 2020, and yes, I will be revising my guide for that exam. I’m aiming to get it out by around February 2020.
In the meantime, if you are self-studying for the exam and absolutely cannot live without a book now, you can use a combination of the current AP Lang/Comp book and either The Ultimate Guide to SAT Grammar, fourth or fifth edition OR The Complete Guide to ACT English.
The major change to the AP exam involves the introduction of SAT/ACT-style writing passages, and from the document released by the College Board, it appears that there will be a heavy focus on “is this sentence relevant?” questions. These are discussed in great detail in the grammar books.
For practice, you can do SAT/ACT Writing passages, with a focus on the rhetoric questions. If you’re already comfortable with them, you probably won’t need to do too much more to prep.
If that’s not enough for you, I would also recommend getting the old (pre-2016) SAT official guide and doing the Fixing Paragraphs questions; since the AP exam (unlike the current SAT) will presumably continue to be written by ETS, it’s reasonable to assume the content will be extremely similar.
Although the essay-scoring rubric will be changed, the essays themselves will remain the same. If you’re a sold writer, you don’t need to worry.
The bottom line is that there’s plenty of material out there that will be directly relevant to the updated exam, even if it doesn’t have “AP English Language and Composition, 2020” stamped on it.
And finally, I feel obligated to point out that if anything, the new version of the test will if anything be easier than the old. The reading passages will be shorter and have fewer questions, and the writing passages will be written at a considerably lower level than any of the multiple-choice passages on the current exam. If the College Board wants to continue to “expand access” to the AP program—and collect even more of those $94/exam fees it’s now insisting that students pony up in October—it needs to ensure that pass rates don’t dip too low.
Follow the money, baby. Follow the money.
