Test prep


This collection is being developed for the revised MCAT® exam that will first be administered in spring 2015. Videos will be added to the collection through fall 2014. All content in this collection has been created under the direction of the Khan Academy and has been reviewed under the direction of the Association of American Medical Colleges (AAMC). All materials are categorized according to the pre-health competencies tested by the MCAT²⁰¹⁵ exam; however, the content in this collection is not intended to prescribe a program of study for the MCAT²⁰¹⁵ exam. The content is also included in the Pre-health Collection within MedEdPORTAL’s iCollaborative sponsored by the AAMC: www.mededportal.org/pre-health *MCAT® is a program of the AAMC and related trademarks owned by the Association include Medical College Admission Test, MCAT, and MCAT²⁰¹⁵.

Gene control

1B: Regulation of genes occurs at every step of the pathway for gene expression. Gene control is critical to the health of the cell, especially with regards to oncogenes and tumor suppressor genes. By Tracy Kim Kovach.

Evolution and population dynamics

1C: How do organisms evolve from one form to another? Learn about all of the different driving forces of evolution and how there might be a few more than just natural selection. How can populations evolve and adapt to changes in their environment? Do groups of organisms behave differently than individuals? By Ross Firestone.

Principles of bioenergetics

1D: What are the thermodynamic principles that are fundamental to understanding metabolism? Learn about Gibbs Free Energy, Enthalpy, and Le Chatelier's Principle. By Jasmine Rana.

Carbohydrate Metabolism

1D: What are the key metabolic pathways that are intimately involved in breaking down or building up glucose? Learn about glycolysis, gluconeogenesis, and the pentose phosphate pathway and how they fit into cellular respiration as a whole. By Jasmine Rana.
