I thought the angles - as far as size goes - were about the same as Kaplan, they were definitely harder though! Maybe she was doing the material on a higher resolution screen, and so they looked smaller?
I believe the size wasn't much different. But in terms of difficulty, the angles on my exam were harder than anything I saw on KAPLAN, TopScore, and CDP. They almost looked alike and differed from one another by maybe 3-4 degrees if not less.
