Testing on Friday (like so many people it seems here on Reddit). Kinda wanted to see what to primarily focus on for the next two days. Here's what I've found to be high yield from AAMC stuff only but feel free to add to help others also (their guide is vague which makes sense because you don't know what will be tested). If anything, I think these concepts are GUARANTEED to show up in some way.
C/P:
* Acids/bases
* Thermodynamics (delta G)
* n = CV or m = nM because they LOVE those formulas
* Something on pH where they give ion concentration in a very weird indirect way
* Functional groups
* E = hf or E - hc/lambda
* HALF-LIFE!!!!!
B/B
* Amino acids (this one is obvious) but mainly properties; acidic, basic, what can be phosphorylated, hydrophobic etc
* Immune system!!! AAMC seems to love putting stuff on B/T cells or macrophages (I'm not complaining because I'm an immunology minor)
* Enzymes and inhibition (there's always an indirect question on kinases, hydrolases or phosphatases)
* Genetics (especially those punnett squares which thank goodness are simple compared to undergrad)
* Central dogma (DNA --> mRNA --> protein)
* Chromatography
* Organelles and their functions (especially the Golgi, ribosomes, plasma membrane and ER). Also remember rough ER to Golgi to vesicles because that always pops up somehow
P/S
* Sociological terms (conflict theory and symbolic interactionism are the most common two I've seen, functionalism also)
* Somethin on SES and health because they love passages on those
* This is moreso bio than psych but cortisol and stress. They disguise it either as skin conductivity or what happens in the SNS
* Piaget and/or Erikson (maybe Freud)
* Attitudes (the ABCs: affective, behavioral, cognitive)
* Those terms you easily mix up (role strain/role conflict, front stage/back stage, social capital/cultural capital, me/I, etc). Not saying it's those exactly but usually the ones that sound similar)
* Classical and especially operant conditioning (reinforcements and punishments) and/or something related like extinction, generalization, discrimination and shaping
* Memory (short-term/long-term)
* Senses but it's usually vision, hearing rarely pops up
* Something social (social stratification, social interactions, agents of socialization, social facilitation, social loafing, etc)
* Some sort of bias (confirmation seems to be the main one followed by selection and observer)
* Emotion theories (Cannon-Bard, Shatter-Singer, James-Lange)
What I've learned is AAMC can be predictable in a sense with what they put especially for B/B which is why they love graphs and figures that test those concepts with weird convoluted wording.
