Balancing equations and predicting reaction products require a kind of pattern recognition that doesn't come naturally to most students. Erica digs into stoichiometry, equilibrium, and acid-base chemistry by connecting each concept to a tangible example — something her predentistry background makes second nature. She graduated with high honors from Harvard and is entering Columbia's dental program, so she's lived the chemistry-heavy coursework her students are navigating.

Substitute teaching STEM to college-prep high schoolers gave Noel a front-row seat to the exact moments chemistry loses people — usually when the logic of electron configuration or periodic trends has to translate into actual problem-solving with moles and reactions. His public policy background at UChicago might seem unrelated, but it trained him to break complex systems into cause-and-effect chains, which is exactly how chemistry works at every level. Rated 4.9 by students.

Breno is earning his Doctor of Science in Chemistry at Harvard, which means he doesn't just remember general chemistry — he's actively expanding it. He tackles everything from stoichiometry and equilibrium to thermodynamics and kinetics by tying each concept back to the underlying physical picture, so students build reasoning skills they can apply to unfamiliar problems.

Stoichiometry, equilibrium, acid-base chemistry, thermodynamics — Zachary tackles each of these by grounding abstract rules in the molecular reality underneath them. His dual background in biology and molecular biology means he naturally connects chemical principles to biological applications, which is especially useful for pre-med and pre-health students who need chemistry to stick long-term.

Stoichiometry, equilibrium, thermodynamics, acid-base chemistry — Marc tackles these core chemistry topics with the perspective of someone who uses them daily in medical and biochemical research. His 5.0 rating comes from an ability to make quantitative problem-solving feel intuitive rather than formulaic.

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 how to bridge the gap between knowing the material and doing well on the test. I am always excited when a student finally has that "ah-ha" moment and declares that they now can see how all of these seemingly separate scientific topics are actually all related. The MCAT no longer seems scary, but turns into a means of truly learning this material and providing a strong foundation for the future.

Balancing equations and predicting reaction products clicks faster when you understand the "why" behind electron behavior — and Jennifer's biomedical engineering background means she teaches chemistry through that lens of atomic-level logic. She breaks down stoichiometry, molarity, and thermodynamics by connecting each concept to real applications she encountered in her own coursework.

Sarah's approach to chemistry leans heavily on dimensional analysis and conceptual reasoning, two skills she sharpened across her public health and biomedical science coursework. Whether the topic is stoichiometry, gas laws, or equilibrium expressions, she walks through the logic step by step so students can tackle unfamiliar problems on their own.

Studying pharmacy at Northeastern means Amy lives in chemistry — from reaction stoichiometry and equilibrium to the thermodynamics behind drug interactions. She brings that daily immersion into her tutoring, unpacking problems step by step so students can trace exactly where a calculation goes from setup to answer. Her 4.9 rating from past students suggests the approach works.

From stoichiometry and equilibrium to thermodynamics and acid-base reactions, Anthony tackles chemistry the way an engineer would — systematically, with an emphasis on understanding the logic behind each step. His dual-degree training in biomedical engineering at BU and Tufts gave him deep fluency in both general and applied chemistry.

After completing a full chemistry sequence as part of her exercise biology degree, Emma tackles general chemistry with a focus on the conceptual logic behind each topic — why electron configuration dictates bonding behavior, how intermolecular forces explain phase changes. She's especially effective at connecting the math side of chemistry (molarity, gas laws, enthalpy) to the conceptual side so neither feels disconnected.

A lot of chemistry tutoring stays at the surface — balancing equations, plugging into formulas. Patrick digs into the molecular-level reasoning behind concepts like equilibrium, thermodynamics, and reaction mechanisms, drawing on the quantitative rigor of his PhD research. His 5.0 rating speaks to how well that deeper approach lands with students.
