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 […]
Scientific Journals for MCAT Passage Reading Practice
When it comes to the MCAT sciences, content is only the first step. Content will give you a foundation for understanding what is happening in any given passage or question. But true mastery of the MCAT comes from being able to do MCAT style passages and questions. For many students, the research and data process […]
Cyclohexane Chair Conformations Axial and Equatorial Stability
“Why does cyclohexane have to be in a chair conformation? How do I know which carbon goes up or down?” Learn this and more in video 1 of the chair conformation series. Learn how to recognize a chair, what it represents (with a model kit and on paper) and the nature of axial and equatorial substituents. (Watch […]
Acid Base Equilibrium Organic Chemistry Practice Questions
Ranking acids and bases are about more than just knowing which is stronger/weaker. This video walks you through a few practice questions where you’re asked to determine the position of equilibrium for acid-base reactions WITHOUT using PKA values. Instead, we’re using CARIO to determine which acids and bases are stronger and predicting the reaction direction […]
Enantiomeric Excess Percent Optical Purity Calculations and Logic
Enantiomeric excess percentage (aka optical purity percentage) calculations are one of the few equations you’ll come across in your orgo course. This video gives you a step by step breakdown and practice examples. You’ll see how to find the percent excess via logic and see the numbers side by side. (Watch on YouTube: Optics 3. Click […]
Cyclohexane Ring Flip and Boat Conformation
Cyclohexanes are most stable in the chair conformation. This requires a ring flip to interconvert between the 2 chair conformations, with some funky (boat) intermediates. This video walks you through the ring flip and boat conformations both with a model kit as well as how to draw the ring flip and boat on paper. (Watch […]
3 Reasons to Take Notes In Class
In addition to paying attention in class, lecture notes can be your most powerful study resource. Yet many students don’t bother with it, thinking they can get necessary information from their textbook, PowerPoint presentation, or the student in the next row. This is not the case. Taking notes is not only about having a ‘set […]
Flashcards – The Secret to Memorization When Study Time is Limited
Do you find your day too busy for proper studying? Do you find that memorizing a list of topics, definitions or concepts is not effective after a long day? Do you need more time to study? One simple solution will (help) solve all the above problems. Flashcards Picture this: you’re preparing for an upcoming history […]
