A 3 Month MCAT Study Plan

MCAT 3 Month Study Plan Leah4sci Sample for PDF Download

If you were retaking the MCAT and hand just 3 months to prepare, what would you do? This is a question I often hear from students who postpone their MCAT, or students who are dissatisfied with their scores and looking to retest. I was very hesitant to publish this plan given that I believe you […]

2020 MCAT Test Dates

Canada 2020 MCAT Test Exam Dates Leah4sci

Taking the MCAT in 2020? The dates are finally out though registration doesn’t open until late October. Looks like once again we have 2 different testing calendars for the US and Canada with more Canadian dates later in the cycle, perhaps to accommodate the rolling admissions for hard deadlines?   Most Canadian medical schools have hard deadlines. […]

Balancing Chemical Equations with Practice Problems

Balancing Chemical Equations Stoichiometry Series by Leah Fisch

When it comes to balancing chemical equations, it’s very easy to get lost and confused by all the changing numbers. The videos below will show you a simple yet efficient approach to make sure you quickly account for all your numbers (minimal guessing) and don’t lose track of your work along the way. Balancing Equations […]

Conventions for Writing Chemical Equations – Arrows, Phases, Coefficients and more

Conventions for Writing Chemical Equations MCAT General Chemistry by Leah Fisch

When it comes to writing chemical equations it’s easy to confuse all the little letters and numbers. What do they mean? Where do they go? This video breaks down every letter and number you’ll see in chemical reactions, from coefficients and phases to numbers that represent charges, multiple atoms or polyatomic ions. (Watch on YouTube: Chemical […]

Common Types of Chemical Reactions

Common Types of Chemical Reactions in MCAT General Chemistry by Leah4sci

While the MCAT will not test you directly on the different types of chemical reactions, you will be expected to know them as they show up in more complex questions, passages, and experiments. This video walks you through the common types of chemical reactions including Disproportionation, Single Replacement, Double Replacement, Combination or Synthesis, Decomposition, and […]

Oxidation and Reduction Reactions

Oxidation and Reduction Reactions in MCAT General Chemistry by Leah4sci

Oxidation and Reduction reactions happen all the time in a living system and thus very likely to show up on the MCAT. This video walks you through oxidation and reduction reactions, how to figure out the half reactions, and how to easily recognize (+ trick) what gets oxidized and what gets reduced. You’ll also see […]

Amino Acid Peptide Linkage Formation and Hydrolysis Reactions

Amino Acid Peptide Linkage and Hydrolysis Reactions MCAT by Leah Fisch.png

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.
