I see How might they be different in terms of style of questions? Are questions more generalized or more based on the passage? Just so I get a sense of what I can extrapolate from my scores on the question packs. Thanks again in advance!
They are focusing on more research based questions. Lots of questions are data interpretation and a lot of people have stated that many of the answers are in the passages, one just has to know how to critically think and analyze it.
The best way to understand the style is to look at AAMC 2015 material. I recommend doing the OG because you want to save the FL till a later (closer to your test date). You can also look at Khan Academies passages, for the bio atleast a lot of them are research/data heavy so they can give you an idea (although Khan Academy passages are hit and miss and definitely harder and more detail oriented.)
