Can I Buy Old Review Books for AP Tests?

I heard that AP tests were updated this year for 2020, and I’m wondering that if I get an old one, maybe 2017 or 2018 or even 2019, if it would still help. The exams I’m taking are
Pysch, Lit, Stats, Macro, and Comp Sci A, so please let me know if I need review books specifically for 2020 or if any review book is ok.

Ya know this probably should be in the AP Tests Preparation forum so if someone could move this that would be great.

None of those exams have changed in recent years and will not change for 2020. The only change for Lit is a change in the scoring rubric, but that does not matter for prep. So new review books are not necessary.

also, before you buy check your school & local library- ours has quite a lot of review books (not all of them though).

While the companies that write the books will tell you every year is “new and improved”, the definition and math behind Freshman Statistics hasn’t changed much in a long, long time…

AP tests are infrequently changed, and you can find info on the College Board site. World History changed substantially this year, so that would require a new book (not sure any are out yet - the Princeton Review version we ordered long ago is supposed to arrive Tuesday).

I don’t recall the details, but I’m not aware that any of yours have changed.

On the flip side - new Barron’s CSA is $13.31 on Amazon, used is $10.72, new Statistics is $16.50, used is $15.57, so…

The only problem is that on the college board website, for all the ap tests it says that they’ve been updated for the new 2020 curriculum. Does this change anything?

It does not say that. They have changed processes (like registering for exams in November). They have changed resources (like the advent of AP Classroom). The exam structure/content (except for AP World History) has not changed. But if you want to buy all new books, certainly feel free.

Can you provide a link and cut/paste the specific wording? This would be surprising if it’s anything more than an overarching statement.

@RichInPitt at least for ap lit, https://apcentral.collegeboard.org/courses/ap-english-language-and-composition?course=ap-english-language-and-composition , in the box on the far left, it talks about how everything is new. The others are more or less like that.

That is just saying what I said in post #6. So to recap, except for APWH, the tests themselves are not changing.
