MCAT Basics is a MedSchoolCoach podcast that teaches MCAT content through topic-by-topic lessons. The topic list is drawn from official AAMC practice materials and third-party resources, and one lesson ties its material directly to section 3A of the AAMC content outline. A run of titles shows the spread: 'Atomic Chemistry', 'Kinetics and Solubility', 'Biosignaling', 'Glycolysis', 'The Krebs Cycle', 'Psychological Disorders'. That run covers general chemistry, biochemistry and psychology, not just biology. Sam Smith hosts. Alex Starks appears as guest host on 'Biosignaling', 'Glycolysis' and 'The Krebs Cycle'. The teaching is detailed, and it moves in order. In 'Atomic Chemistry', the four quantum numbers arrive one at a time: principal, azimuthal, magnetic and spin. The principal number is tied to the integer in labels like 1s and 2s. 'Glycolysis' goes molecule by molecule and marks the phosphofructokinase 1 reaction as the point where glucose is committed to the pathway. 'The Krebs Cycle' follows carbons as they leave as CO2 and tracks how the energy from cleaving succinyl-CoA ends up as ATP. 'Biosignaling' traces receptor tyrosine kinases from the ligand-binding region to the intracellular domain, notes that these signaling pathways are often implicated in cancer, and promises a short quiz at the end. Test strategy is part of the explanations. In 'Kinetics and Solubility', Sam Smith warns bluntly against reading a rate law off stoichiometric coefficients unless a reaction is stated to be elementary, and points students to the experimental data instead. The same lesson covers the solubility constant Ksp, the common ion effect, selective precipitation, the Arrhenius equation and the way pressure raises a gas's solubility. The register is conversational. Fun facts get dropped in, abbreviations are flagged so a listener can keep up, and at one point the Krebs cycle lesson admits that losing a second carbon will have to serve as the fun fact for a step. 'Psychological Disorders' shows a more reflective side. Sam Smith starts from the question of what counts as a disorder at all, admitting that the line between a disorder and everyday anxiety, doubt or sadness has not always been clear to him. He then lays out categories from anxiety disorders to personality disorders, along with the biological bases of schizophrenia, depression, Alzheimer's and Parkinson's. Sponsorship from MedSchoolCoach, which offers MCAT tutoring and medical school admissions advising, frames the lessons, and one lesson closes on advice to seek out mentors. What a listener gets is spoken review of specific exam content, organised closely enough to line up with whatever chapter is open on the desk.
