Kaplan unlimited prep

I’m looking for SAT and ACT prep classes, and I saw that Kaplan has a package for $1499 that includes prep for the PSAT, ACT, and the SAT. This is suspiciously cheaper than programs like Elite, etc.
Has anyone taken this, and would you recommend it? How beneficial is this program in helping me improve my scores? I’ve heard they have terrible customer service though, but I don’t know how good they are at helping students improve skills for the tests.

I have heard Kaplan and PR are best for lower scorers who need a lot of content review.

I suggest Khan Academy for PSAT/SAT and Prepscholar for all three.

@nw2this thanks!
