For me it completely depended on the passages. I thought 3 was the hardest and got my lowest score (it was also my first...) and I thought 7, 8, and 9 were easiest, but not by a ton, than the earlier ones. I took them in the following order: 3, 10, 9, 8, 7, 4, 5, 6. I don't know why I did this but whatever. Overall my score only really deviated by +/- one point on every test, almost always hitting my average on the nose. I varied on each section though by +/- two points. There were a few passages that I thought were totally representative of the real test, ussually one or 2 per section per test. The most representative are as follows:
These were in PS:
The earthquake doppler passage
The particle accelerator passage
The counting avagadros number passage
The electrolysis of solids passage
The melting of solids passage
In BS:
The evolution of lizards passage
The firefighter response passage
The respiratory system 4 question passage
The tetrahymea reproduction passage
The developing embryo juxtaposition passage
Pretty much all the ochems except the CBT 6's
Ussually the real MCAT passages questions are like these in difficulty, but are longer in format and contain much more extraneous information. If I could do it over I wouldnt change anything except taking these tests while freaking out with your classmates or study partners in a library or similair location, to better get in the mind set for test day although this still might not completely prepare you.
