Enantiomeric Excess Percent Optical Purity Calculations and Logic

Enantiomeric Excess Percent Optical Purity in Series by Leah4sci

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 […]

Polarimetry in Optical Activity

Polarimetry Optical Activity in Chirality and Stereochemistry by Leah4sci

Polarimetry is the key to understanding chiral molecules in terms of optical activity. This video goes behind the scenes of the polarimeter to help you understand what plane polarized light has to do with chiral molecules. Part 1 (of 3) in this mini series explains + D and – L, dextrorotatory and levorotatory, and their (lack […]

Overwhelmed and Missing Out for a 515 MCAT Score

Maggie Interview MCAT feedback 2017 Leah4sci keep my sanity

Studying for the MCAT can feel like drudgery work filled with anxiety. Stuck inside, hunkered down, head buried in a book while your friends and the whole rest of the world is passing you by. It is hard work! But it doesn’t have to be that dreary and scary. After all, hard work pays off! […]

Orgo Mechanisms with Common Arrow Patterns

Organic Chemistry Mechanisms Part 3 in Video Tutorial Series by Leah4Sci

Organic chemistry is all about mechanisms. And while the sheer volume may feel overwhelming, they all boil down to a few simple types of mechanism steps. In Part 1 and Part 2 we looked at the four common mechanism types: Nucleophilic attack, Loss of Leaving Group, Proton transfer and Rearrangements. In this video we’ll look at TWO […]

Proton Transfer and Rearrangement Mechanisms in Organic Chemistry

Organic Chemistry Mechanisms Part 2 in Video Tutorial Series by Leah4Sci

Proton transfer and rearrangements are 2 more common mechanism patterns you will face in organic chemistry. This is in addition to Nucleophilic attack and Loss of Leaving Group discussed in Mechanism Video Part 1. You’ll see multiple proton transfer examples in action including turning a bad leaving group into a good leaving group! Rearrangement mechanism are broken down for […]

2018 MCAT Dates

2018 MCAT Test Date Calendar Schedule

Are you thinking of taking the MCAT in 2018? The dates are finally out! (registration doesn’t open for a bit longer) What you’re looking at here: The MCAT is typically given a number of times in January – this is the winter schedule. The regular MCAT testing cycle is from April through September. After you […]

Intro to Orgo Mechanisms Nucleophilic Attack and Loss of Leaving Group

Mechanisms Part 1 in Organic Chemistry Tutorial Video Series by Leah4Sci

Organic chemistry is all about the reaction mechanisms and moving arrows. Video 1 in this Mechanism series will help you understand what the heck these mechanisms are all about. We’ll start with a quick overview of what to look for, how to write the mechanisms, reaction arrows, and more. Then we’ll look at the first […]

What To Expect in Organic Chemistry

what to expect in orgo

Organic chemistry is one of the most difficult sciences you’ll take in undergrad. Many students fail and have to take it again. You’ve heard the rumors. Perhaps you don’t believe them, or perhaps you’re terrified. But what can you actually do about them? The first step to conquering an unknown beast is understanding it. By […]

MD Bound Despite 2.7 Undergrad GPA

MD bound despite 2.7 undergrad gpa

When your dream is to become a doctor, it’s easy to get overwhelmed and scared. It’s easy to feel the anxious sense of ‘I must apply to 100 schools, get accepted to 50, and hopefully reach my dreams!’  Now I agree, you want to apply to multiple schools. But in the end, one acceptance is […]
