When it comes to acid base calculations on the MCAT, weak bases are potentially the most confusing. Not only do you have to convert from pOH to pH, but you may also find yourself having to find the kb from a given ka to start the process. And worst of all, you learned all this […]
pH and pOH for Strong Bases in MCAT Chemistry
Acid base calculations get trickier when dealing with bases since most MCAT style questions will ask about pH instead of pOH. This means you have to be comfortable calculating both OH- and H+ concentrations to find pOH and pH values. This video breaks it down with a few examples. (click to watch on YouTube. Video […]
What Every Student Needs To Know About Studying In The Bathroom
Have you ever considered how much time you waste when you’re in the bathroom? Do you ever do something to pass the time while you’re on the can? For example, read a magazine or book, answer text messages or emails, etc. Here’s a trick to learn more information and minimize study distractions without adding any […]

You open your book to study, find yourself getting more and more frustrated, and just give up. You know you need to study, but keep finding good reasons to procrastinate until the day before the […]
Too Many MCAT Notes?
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 […]
Orbital Hybridization and Acid Base Strength
Video 7 in the acid/base tutorial video series helps you understand the effect of hybridization on acid base strength. This video discusses WHY sp hybrids are more acidic and sp3 hybridized atoms more basics. This video also shows you how to calculate percent ‘s’ character (click HERE to watch this video on YouTube or check Transcript […]
Banned from Taking the MCAT
As an MCAT Tutor, it’s natural to assume I’ve taken the exam for myself, maybe multiple times. “So you tutor for the MCAT? When did you take the new exam and how did you score?” Fair enough questions, right? Since the new MCAT was first rolled out in April 2015, this has been asked by […]
Sodium Borohydride Carbonyl Reduction Reaction and Mechanism
Sodium Borohydride NaBH4 is a common reducing reagent used with carbonyl compounds. NaBH4 is a weak reducing agent and will only reduce ketones and aldehyes. Watch for the explanation below including reaction, mechanism, and practice problems. (Watch on YouTube: NaBH4 Reduction.
