Balancing equations, understanding molarity, and predicting reaction products are all things Lisa does routinely in her marine biogeochemistry lab at Stony Brook. She approaches high school chemistry by grounding each new topic in a concrete example so students see the logic behind the math, especially in tricky areas like equilibrium and acid-base chemistry.

Fourth-year medical students don't usually think about stoichiometry or gas laws anymore, but Michael's path through Albert Einstein College of Medicine — plus his biology degree earned summa cum laude — means he's built on those high school chemistry foundations repeatedly in biochemistry, pharmacology, and physiology. He also spent time tutoring Regents-level chemistry and teaching MCAT prep for Kaplan, so he knows exactly where the gaps tend to form around topics like nomenclature, mole calculations, and balancing equations, and how to close them quickly.

At a preparatory school where she manages and teaches daily, Moriah has spent real time walking students through science material one-on-one — including the kind of systematic problem setup that chemistry demands for topics like stoichiometry and dimensional analysis. Her strength is reading how a student processes information and adjusting the explanation on the spot, which matters in a subject where one shaky concept (like mole ratios) can derail an entire unit. Rated 5.0 by students.

Balancing equations and stoichiometry problems click faster when you understand what's actually happening at the molecular level — and Laura's biology coursework at WashU in St. Louis means she's constantly applying chemistry concepts like bonding, reaction energetics, and solution behavior in biological contexts. That dual perspective lets her explain why a concept like electronegativity or gas behavior matters beyond the chemistry classroom, which tends to make the logic memorable rather than disposable. Rated 5.0 by students.

His Penn State science background and medical school training mean he knows exactly where these fundamentals lead.

Stoichiometry is where most high school chemistry students start to struggle, because it demands both conceptual understanding and careful unit tracking at the same time. Brandon approaches it the way engineers do: systematically, with dimensional analysis as the backbone of every calculation. His 5.0 rating speaks to how well that structured method clicks for students.

Dental school at Penn requires a command of chemistry that most people don't associate with dentistry — understanding how composite resins bond, why certain anesthetics work at specific pH levels, and how fluoride interacts with enamel at the molecular level. Josh brings that applied chemistry lens to high school topics like bonding, acids and bases, and solution chemistry, giving students concrete examples of where these ideas show up beyond the textbook.

Doing a PhD in genetics and neuroscience at Rockefeller while pursuing his MD at Weill Cornell, Daniel lives in a world where chemistry isn't abstract — electron behavior, bond energies, and reaction equilibria show up every time he reads a paper or designs an experiment. He teaches stoichiometry and gas laws by anchoring the math in the molecular reality underneath, so the calculations feel like they're describing something rather than just producing an answer.

After completing Columbia University's premedical certificate program — where he worked through college-level chemistry, biology, and physics — Timothy returned to chemistry with the kind of intentionality that comes from choosing the subject as an adult rather than just checking a box. He digs into the stoichiometry and nomenclature questions that trip up high school students by connecting them back to the underlying atomic behavior, making the problem-solving feel logical rather than arbitrary. Rated 5.0 by students.

Balancing redox reactions or predicting molecular geometry often trips students up because the rules feel arbitrary without a deeper framework. Colin earned his biology degree at Washington University in St. Louis with extensive chemistry coursework, so he teaches concepts like periodic trends, stoichiometry, and acid-base equilibria by showing how each idea builds on the last. That structural approach turns memorization-heavy chapters into something students can actually reason through.

Balancing equations and predicting reaction products gets a lot easier when you can laugh through the tough parts — Elsia turns tricky stoichiometry and mole conversions into competitive problem-solving races that actually make the concepts stick.

She's particularly sharp at connecting molecular-level behavior to the math that describes it.

Pre-med biology coursework and a seven-year BS/DO program at NYIT mean Taran has taken chemistry well past the high school level — general chem, organic chem, biochemistry — and knows which early concepts (like naming compounds, solution chemistry, and dimensional analysis) matter most for what comes next. He teaches the problem-solving logic behind each topic so students build real fluency instead of just surviving the next exam. Rated 5.0 by students.

Mole conversions, electron configurations, acid-base equilibria — high school chemistry asks students to juggle a lot of conceptual frameworks at once. Jacob's astrophysics training gave him strong command of the physical chemistry principles underlying these topics, and his instinct as a playwright is to strip an explanation down to its clearest, most compelling form.

The jump from middle school science to high school chemistry often catches students off guard — suddenly they're expected to think in moles, track electron configurations, and solve dimensional analysis problems. Adam tackles these early stumbling blocks by making the periodic table feel like a map rather than a wall of symbols. His approach emphasizes understanding trends and relationships so that predicting chemical behavior becomes intuitive, not just an exercise in memorization.
