Without a Calculator! Scientific notation on the MCAT is a common source of panic, because unlike simple long multiplication and division, it’s hard to fall back on pen-and-paper method. This MCAT […]
Factor Of 10 Shortcut in MCAT Multiplication and Division
This tutorial continues from MCAT Math Video 2 where I show you how to use the factor-of-10-trick to quickly multiply and divide any number by a factor of 10, 100, and so on. However, many of your MCAT chemistry and physics calculations will not be this clean and easy. But you certainly cannot afford to […]
Multiplication and Division for Units of Ten
As you’re working through the physical sciences section of your MCAT you will be faced with unit conversions asking you to multiply or divide numbers by some factor of 10. This can occur in questions such as gram to kilogram or liter to milliliter conversions. Given the time constraint on the MCAT and lack of […]
Introduction To MCAT Math Without A Calculator
While the pre-2015 MCAT only tests you on science and verbal, you are still required to perform complex mathematical calculations WITHOUT A CALCULATOR! Unfortunately, studying the sciences alone won’t help you here as the math equations tend to trip up students in many ways: You may get stuck in knowing how to apply math to the […]
Mole and Avogadro’s Number in MCAT General Chemistry
Moles and Avogadro’s number are big! And they come across as overwhelming. But YOU can master them! This video covers the definition of Moles, with an illustration showing the logic of moles in general chemistry. You’ll also see how to easily and quickly convert from and to them on the MCAT. You’ll see conversions including […]
Amino Acids 3 Polar Acidic and Basic Side Chains
Hydrophilic amino acids are much more reactive and interactive compared to hydrophobic side chains. This video breaks down the hydrophilic amino acids including polar neutral, acidic and basic side chains. (Watch on YouTube: Polar/Acidic/Basic Amino Acids. Click cc on the bottom right for video transcript) Referenced in this video: Acid Base Tutorial Series Zwitterion Tutorial […]
Amino Acids 2 Hydrophobic Non-Polar Side Chains
Hydrophobic amino acids have neutral non-polar side chains. Given the lack of polarity these groups have no means to interact with an aqueous biological environment. This video breaks down each of the hydrophobic amino acids to help you understand the name, 1 and 3 letter abbreviations, and side chain functional groups. (Watch on YouTube: Hydrophobic […]
Conventions for Writing Chemical Equations – Arrows, Phases, Coefficients and more
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 […]
Percent By Mass Composition MCAT General Chemistry
All the composition by percent mass questions don’t have to be confusing. You can use them to get the information you need! Learn ONE rule for them all! This video makes this concept simple. You’ll see WHY and HOW these equations work, instead of memorizing all the different percent formulas. You will see examples worked step-by-step my […]
Molarity Molality and Molar Mass for MCAT General Chemistry
Molarity, Molality, and Molar Mass calculations can get overwhelming FAST on the MCAT. This video shows you how to easily calculate each of these concepts as well as some time saving shortcuts with a few examples. You’ll learn the differences between molarity vs molality as well as fun trick for quickly estimating between them on the MCAT! (Watch […]
