MCAT Basics (from MedSchoolCoach)

Atomic chemistry is a core component of the MCAT, essential for understanding molecular behavior and periodic trends. 
In this episode, host Sam Smith explores key concepts in atomic chemistry, including the intricacies of quantum theory, hybridization, and molecular geometry. You'll gain insights into electron configuration, periodic trends, and the role of quantum numbers in describing electrons. Sam also discusses the significance of nuclear decay, from alpha to beta and gamma decay, and how it impacts atomic structure.

In this episode, we explore key topics in genetics, including how sex-linked and autosomal traits are inherited. We'll break down inheritance patterns using real-world examples, like X-linked recessive diseases, and walk through Punnett square problems to show how these traits are passed down.
We also cover the regulation of gene expression, focusing on epigenetic changes such as DNA methylation and how genetic imprinting impacts which genes are expressed. You'll gain insight into transcriptional and post-transcriptional control mechanisms in prokaryotes and eukaryotes, along with the processes of DNA repair that maintain genetic stability.
Finally, we discuss important genetic lab techniques, such as PCR, blotting methods, and fluorescence in situ hybridization (FISH), and how they are used in gene analysis and diagnostics.

Mastering the concept of sociological groups can unlock a deeper understanding of how we interact and influence each other. On top of that, social interactions and group dynamics form the backbone of the Psych/Soc section of the MCAT, so mastering this topic is key to a good score. 
In this episode, host Sam Smith breaks down the essential topic of sociological groups. You’ll gain a comprehensive understanding of the different types of groups, the dynamics within organizations, bureaucracy, and social networks, and key concepts like groupthink, group polarization, and social loafing. We also explore how these concepts apply to real-world examples, from business partnerships to historical events like the Salem witch trials.
