Kaplan Physics

Hey everyone, I've seen some things around other posts but they tend to be fairly old so I wanted to bring this up.

I'm studying for Physics with Kaplan 5th ed. stuff and it just seems incredibly hard. Course that could be me as well. Anyway, those of you who have taken the OAT, what did you think of the physics section and how it compared to the Kaplan stuff? Harder/ Easier?

I've got the Physics Destroyer as well, and same question as above. Harder/ Easier?

I appreciate any...
