A lot of our old SAT program information still works on the redesigned test because it is general test-taking strategies. The main difference is in formatting since the SAT looks more like the ACT now. (Many of the ACT writers are working for the College Board now.)
I would omit the writing and essay section since those are a completely different format now. The reading adds 2 new types of questions and the math has less geometry and more advanced math.
The writing section is completely different and the essay is now written from a published piece of work and not from a prompt question.
Also, the old DVD program is still valuable because it also contains information that can work on other tests such as the ACT, GRE, AP…
