🔴 **LIVE TONIGHT: Do Unit Conversions Make Your Brain Freeze?**

Even if you know the math...

Too many numbers.
Too many steps.

And which way does the decimal go again? 🤔

Tonight, we’re fixing that.

I’ll show you how to:

✅ Know when to multiply, divide, or move the decimal
✅ Quickly figure out if your answer should get bigger or smaller
✅ Convert between units without a calculator
✅ Use simple mental math shortcuts to save time
✅ Skip the long dimensional analysis setup when there’s a faster way

📅 **LIVE Tonight at 8:30 PM ET**

🔴 Lewis structures a little rusty from Gen Chem?

If you memorized this back in gen chem and freeze the moment it shows up in your MCAT prep, you're not alone.

I'm teaching a focused live session this Tuesday at 8:30 PM ET on my Orgo channel where I'll show you exactly how to draw a correct Lewis structure, every time, whether you're starting from a condensed or molecular formula.

You'll Learn:
✔️ How to draw Lewis structures for organic molecules
✔️ Know exactly where to place atoms and electrons
✔️ Recognize common bonding patterns for C, N, O, H, and halogens
✔️ Figure out lone pairs, sigma bonds, and pi bonds
✔️ Calculate formal charge using a simple shortcut
✔️ Turn a condensed or molecular formula into a correct Lewis structure, no guessing required

Whether you're taking Organic Chemistry this semester or preparing for the MCAT, this is one of those foundational skills that makes everything else easier.

🔴 sp3, sp2, and sp hybridization still blending together?

If you memorized hybridization and still find yourself freezing every time it comes up in your MCAT prep, you’re not alone

I'm teaching a focused live session this Tuesday at 8:30 PM ET on my Orgo channel where I'll show you the simple counting trick to identify hybridization, molecular geometry, and bond angles in seconds.

You’ll Learn:
✔️ The simple counting shortcut for identifying sp3, sp2, and sp
✔️ Predict molecular geometry and bond angles in seconds
✔️ Understand how single, double, and triple bonds affect hybridization
✔️ Know where sigma bonds, pi bonds, and lone pairs fit in
✔️ Avoid the most common hybridization mistakes
✔️ Practice problems to build speed and confidence

Whether you're taking Organic Chemistry this semester or preparing for the MCAT, this is one of those foundational topics that makes everything else easier.

I'm thinking of starting back up with MCAT livestreams (been so sick... even past the first trimester but it's feeling doable soon)
Which evenings (around ~8pm Eastern) would work best for you?

If weekday vote below, if weekend please let me know in the comments. Weekends are less likely due to exhaustion from spending the day with my kiddo and no time to nap despite pregnancy fatigue

Excited to finally share this publicly…

After a very long infertility journey, we’re so happy to be closing out this chapter with one more holiday miracle.

Baby boy #2 is due mid-December. 💙

And this is why I haven’t been as present lately.

IVF medication complications, immediately followed by a very rough first trimester, and I’ve basically been in survival mode. Between severe nausea, nonstop medication-induced fatigue, and barely having enough energy to take care of my son and get through the day, Leah4Sci had to slow way down.

That meant fewer emails, no new videos, no livestreams, no Shorts, and a whole lot of things piling up behind the scenes.

The good news is that as I enter the second trimester, while I’m still feeling pretty miserable, I’m finally starting to see signs of improvement. I’ve been able to reduce the nausea medication 🤞 which means I’m finally getting a few productive hours back each day.

Right now, I’m using that time to catch up on emails, messages, student questions, and everything that piled up while I was out of commission.

Thank you for your patience, support, and understanding. Leah4Sci has always been a very personal business, and I wanted to share what was going on rather than disappear without explanation.

I’m looking forward to gradually getting back to videos, livestreams, and more content as my energy returns.

I’ve missed creating for you and learning with you. What would you like to see me create first?

🔴 Are SN1, SN2, E1, and E2 still all blending together?

If substitution and elimination reactions keep feeling like one giant memorization mess, you are not alone.

I’m teaching a focused live session this Monday at 8:30 PM ET on my Orgo channel where I’ll show you how to choose the right reaction without relying on confusing flowcharts or random guessing.

You’ll learn:

✔️ What to look for when choosing between SN1, SN2, E1, E2
✔️ Substrate analysis: alpha/beta substitution patterns
✔️ Strong vs weak nucleophiles and bases
✔️ Polar protic vs aprotic solvents
✔️ Leaving group strength + the role of heat
✔️ Practice problems and live Q&A

If you’re tired of freezing on reaction questions because every rule feels disconnected, this session will help you finally see the logic behind which mechanism wins.

🔴 Tuesday! Aldol & Claisen Condensation Shortcuts

Register here 👉 Leah4sci.com/Orgolive

Aldol and Claisen condensation reactions show up in MCAT organic chemistry, and you need to know what makes them different and how to predict their products.

This Tuesday I'm teaching a focused session on my Orgo channel covering how each reaction works, what makes them different, and shortcuts for predicting products and solving synthesis problems without brute memorization.

You will learn:
✔️ Aldol condensation: the reaction and mechanism step by step
✔️ Claisen condensation: the reaction and mechanism step by step
✔️ Aldol vs Claisen: the key differences so you stop mixing them up
✔️ Product shortcuts: how to quickly identify the final structure on exams
✔️ Synthesis and retrosynthesis: how to work forward and backward with confidence

When you add more resistors to a circuit… does the current go UP or DOWN? 🤔
Most students guess wrong here because circuits don’t behave the way you expect.
In my newest video, you’ll finally see what actually happens when current splits in series vs parallel circuits, why resistance sometimes goes DOWN when you add more components, and the shortcut that makes these questions way easier on the MCAT.
