Too Many MCAT Notes?

too many notes MCAT how to keep good notes leah4sci mcat tutor

You’re premed! You’re a diligent student, and a hard worker. Which means… as you study you take notes. LOTS of notes! Perhaps too many? How neat are your MCAT notes? How detailed are they? As an undergraduate, I prided myself on taking very good notes. Approaching OCD level. I had a collection of colored pens […]

How to Use Your Organic Chemistry Model Kit

How to use your organic chemistry model kit by Leah Fisch

An organic chemistry model kit will be a huge help to understanding this difficult 3-dimensional topic. But where do you draw the line between effective study aid and tedious annoying time-wasting-on-exam crutch? In this video I’ll walk you through how to use your organic chemistry model kit. From the unboxing of my go-to Molecular Visions Model […]

My MCAT Study Distraction List

My mcat study distraction list Leah4sci

I have trouble focusing. I have ADHD and many of my students do as well. In my case, it’s not severe enough to require medication. But enough to get in my way if I don’t focus 100%. As I sit and contemplate it, I think our instant-connection/notification-world has us ALL suffering from some form of […]

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 […]
