She's a visual teacher who sketches out Lewis structures, orbital diagrams, and reaction maps so that abstract concepts become something students can actually picture. Her 5.0 rating speaks to how well that approach lands.

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.

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.

Pre-dental coursework at Vanderbilt took Sarah through the full general chemistry sequence, so topics like stoichiometry, equilibrium, and gas laws are tools she still uses regularly in her science track — not material she's recalling from years ago. She zeroes in on dimensional analysis and mole relationships as the backbone of most high school chemistry problems, teaching students to map out the logic of a calculation before touching a calculator. Rated 5.0 by students.

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.

Running an immunology lab at Columbia means Matthew uses chemistry daily — from buffer calculations to understanding reaction kinetics in biological systems.

Varun's academic background is in government and film rather than the sciences, but his 1580 SAT and broad tutoring experience across math and science subjects mean he's comfortable walking through the quantitative reasoning that trips students up in chemistry — dimensional analysis, mole calculations, and stoichiometry setups. He approaches these topics the way he'd approach a tricky math problem: isolating what you know, identifying the relationship, and building toward the answer one logical step at a time.

Most high school chemistry struggles trace back to a handful of sticking points: mole conversions, balancing redox reactions, or figuring out what's happening in an equilibrium expression. Drisana approaches each of these as a structured math problem, showing students a repeatable setup so they can handle new variations on their own instead of memorizing each example separately.

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.

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.

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.
