Largely, the new MCAT is similar to the old one in that the questions stem from passages. It is probably only in that vein that they are similar. In every other way, they are different exams.
Hence the 528 scale vs 45.
My own prep is including research articles published at any time over the past 20 years that include graphs, diagrams, data tables, and other types of non-verbiage information. Things likely to be seen on the MCAT, in other words.
Below you will find links to articles that I found on reddit. The goal is to read the published research, come to my own conclusions and then see how that matches to the researchers themselves. In a way, this should mimic to a small degree how the new MCAT is tested.
3 Functional Classes of Transcriptional Activation Domains
SNF1/AMPK pathways in yeast
Recognition of Trimethylated Histone H3 Lysine 4
Rat1 in Coupling mRNA
Control of Somatic Tissue Differentiation
Will add more as I find them; waiting on links to genetic predisposition of behavioral issues.
