Pursuing a Doctor of Science in Chemistry at Harvard, Breno lives inside the discipline — which means high school topics like electron orbitals, periodic trends, and reaction stoichiometry are things he can explain from genuine depth rather than rehearsed definitions. He unpacks the atomic-level rea...

Balancing equations, stoichiometry, and periodic trends all click faster when a student understands the 'why' behind each rule. Erica's science background at Harvard — plus her pre-dental coursework in general and organic chemistry — means she can connect high school chemistry concepts to real-world...

Balancing redox reactions, predicting products, and navigating the mole concept are the places where most high school chemistry students get stuck. Noel's college-prep teaching background means he's seen these sticking points up close and tackles them by walking through the reasoning step by step ra...

The jump from memorizing the periodic table to actually using it — predicting why sodium reacts violently with water, or why noble gases don't bother reacting at all — is where most high school chemistry students get stuck. Marc's biochemistry degree and current MD/PhD work mean he's been applying c...

I am also a first year medical student at the Tufts University School of Medicine in Boston. I have extensive experience with premedical classes and have taken and tutored the MCAT exam. I placed in the 97th percentile of the MCAT exam and I understand what the test takers want students to know and ...

Balancing redox equations, predicting reaction products, understanding molarity — high school chemistry is full of moments where one shaky concept can derail everything that follows. Katharine earned her degree in biochemistry, so she knows exactly which foundational skills in stoichiometry and atom...

The jump from memorizing element names to actually applying equilibrium expressions and redox half-reactions trips up a lot of high school students. Jennifer approaches these problems from an engineering mindset, showing how to set up calculations systematically so that topics like acid-base titrati...

Sarah's biomedical science master's work at Tufts Medical School means she's constantly applying chemistry principles — thermodynamics, molecular interactions, reaction kinetics — in contexts that go well beyond a high school textbook. She uses that perspective to teach topics like stoichiometry and...

Balancing equations, stoichiometry, and electron configurations click faster when you break them into smaller, logical steps — and that's exactly how Amy approaches high school chemistry. Her pharmacy coursework at Northeastern means she uses these same chemical principles daily, so she teaches them...

Stoichiometry and gas laws tend to click faster when the person explaining them uses those concepts every day — Zachary's master's in molecular biology means reactions, concentrations, and energy calculations are still part of his working vocabulary, not something he left behind in undergrad. He dig...
