Fischer projections are a key skill required at the organic chemistry and definitely at the biochemistry molecule. Instead of drawing complex 3-dimensional structures over and over, you simply learn how to draw a ‘flat’ version of the molecule without losing its chirality. This video is the first in a 5-part series to help you learn […]
Ionization of Water in MCAT Acid Base Chemistry
Water is a fascinating molecule to study, especially in reference to acid base chemistry. Both amphoteric and amphiprotic (explained in video) it will undergo ionization to yield both an acid and a base. This video breaks it down and covers important related calculations required for the MCAT. (click to watch on YouTube. Read Video transcript […]
Weak Bases pH pOH ka and kb Calculations in MCAT Chemistry
When it comes to acid base calculations on the MCAT, weak bases are potentially the most confusing. Not only do you have to convert from pOH to pH, but you may also find yourself having to find the kb from a given ka to start the process. And worst of all, you learned all this […]
pH and pOH for Strong Bases in MCAT Chemistry
Acid base calculations get trickier when dealing with bases since most MCAT style questions will ask about pH instead of pOH. This means you have to be comfortable calculating both OH- and H+ concentrations to find pOH and pH values. This video breaks it down with a few examples. (click to watch on YouTube. Video […]
MCAT Acid Base Chemistry Conjugates and Reactions
Video 1 in the MCAT Acid Base series is the introduction to acid/base concepts for upcoming calculations. You’ll learn how to recognize the ‘tricky’ acids, bases, and their conjugates, as well as how to relate and differentiate between Arrhenius, Bronsted-Lowry and Lewis acids and bases. Resources mentioned IN the video are linked below the video […]
Amino Acid Peptide Linkage Formation and Hydrolysis Reactions
Amino acids are the building blocks of living things. This makes the process of making/breaking bonds critical to understanding biological sciences. This video walks you through the formation of an amino acid bond – the peptide bond, as well as breaking the bonds through hydrolysis. (Watch on YouTube: Peptide Linkage/Hydrolysis.

Adding and Subtracting Vectors in MCAT Translational Motion Video 3
The MCAT will test your ability to analyze single vectors, as well as solving larger problems combining 2 or more vectors. While the math for adding and subtracting vectors isn’t difficult, it’s important to understand the nature of each vector combination and the logic behind the specific equations used. The video below shows you how […]
Which Equations To Choose in MCAT Kinematics Translational Motion Video 9
As an MCAT tutor, one of the common questions I receive is “How do I know which equations to use?” With so many formulas to memorize it’s hard to keep them all straight, and even harder to pick out one from the many many formuals you’ve studied. The video below breaks down the different kinematic […]
Projectile Motion in MCAT Kinematics Translational Motion Video 8
Projectile motion questions are an interesting phenomenon in your MCAT Physics preparations. Think back to your general physics course, if you had to solve a projectile motions question you likely found yourself spending 20-30 minutes on a question complete with 3-4 unique calculations. However, you won’t have the leisure of time on your MCAT. And […]
Free Fall in MCAT Kinematics Translational Motion Video 7
Free fall is a specific application of acceleration and kinematics, where gravity is the only form of acceleration in a given problem. These questions include objects being thrown up, or objects falling down without any applied acceleration. The video below helps you understand the nature of Free Fall as it will show up on your […]
