I took my test in April. I first started using Kaplan online course. I personally think that Kaplan is a good studying resource and all the information you need to know for the test is there. However, I don't think the Kaplan full length exams really represent the actual test. Some of the questions go into some weird details that you don't need to know for the test. So I guess you can say that Kaplan is harder than the actual test but it is not a good representation of the test. However, the PAT sections in the full lengths are way easier than the actual test.
I did all the full length tests two months before my actual test. I then spent a month to review all the materials and the questions I did wrong on the full lengths. A month before the test, I wanted to do more practice problems so I started using Bootcamp and I surprisingly found that the questions were really different from the ones in Kaplan, so I worked really hard and tried every means to finish all the practice problems. And it was worth it because I think the actual DAT was similar to BC in terms of the wording and difficulty. I found PAT on the actual test slightly harder than BC but I still managed to get a competitive score.
I did not have a record of the scores I got on my Kaplan practice tests. So sorry I could not really answer your question.
