Kaplan was good for strategies, breakdowns, and practice tests IMO. I used Chad's videos to study for ochem gchem and QR. I also used the destroyers for chem, bio and QR. For PAT, I had an app on my phone where I could practice problems in my free time. I was very pleased with my score and have received multiple interviews and acceptances!
No matter what you use, I think the best thing you can do is take as many practice tests as possible.
