Jeffrey
Pre-Calculus Tutor • +29 Subjects
I am enrolled in the Mechanical Engineering PhD program at Rice University which will begin Fall 2020, and I am hoping to return to academia as a professor after earning my PhD. In the meantime, I am looking to share my passion for gaining knowledge, specifically in STEM, by educating the up and coming members of such a great field. I have experience tutoring both Calculus and Physics at Notre Dame, as well as experience as a Student Assistant for Differential Equations and Mechanics. I believe the key to learning is much deeper than learning to solve problems and that seeking knowledge is one of the best means for personal improvement.

Samuel
AP Calculus AB Tutor • +29 Subjects
I am a freshman at Caltech majoring in Applied and Computational Mathematics. My favorite subject to tutor is math because I find it very rewarding to simplify complex topics to aid in understanding. I have lots of tutoring experience. In high school, I ran and taught an SAT prep class and was vice president of my school's NHS chapter where I ran our tutoring program, and I, myself, tutored. I also was a teaching assistant in the summer of 2020 for a class in discrete mathematics through a program called PACT (Program in Algorithmic and Combinatorial Thinking). I love learning and hope to make the process enjoyable for you!

Tony
Calculus Tutor • +28 Subjects
I am a recent graduate of Yale University and incoming first year medical student at Columbia University. Originally from the DC area, I have always had a passion for science and medicine and pursued a degree in Biology while at Yale. During the 2008-2009 academic year, I tutored science, math, English, history, and Mandarin Chinese part-time with a DC-based tutoring company. At Yale, I worked as a freshman counselor to provide academic and career advice to incoming freshmen. I have taken both SAT and MCAT test prep classes and am familiar with both tests as well as the preparation necessary to score well. My personal career goals include attending medical school to pursue either immunology/infectious diseases or psych/neurology, teaching biology at the university level, and working in public/global health with either the CDC or the WHO.

Frequently Asked Questions
The biggest challenge areas are balancing chemical equations, understanding mole concepts, and grasping the relationship between macroscopic observations and atomic-level explanations. Many students also struggle with stoichiometry—converting between grams, moles, and particles—because it requires fluency with multiple conversion steps. Additionally, visualizing molecular structures and understanding why chemical reactions happen at the particle level (rather than just memorizing that they do) trips up many freshmen. A tutor can break these down systematically and use models or drawings to make the invisible visible.
Lab work is essential—it's where students apply the scientific method, make observations, and connect theory to reality. However, many students struggle to interpret lab results, write proper conclusions, or understand why their experiment didn't match predictions. A tutor can help you design experiments thoughtfully, troubleshoot when results seem off, practice proper lab technique and safety protocols, and develop the reasoning skills to explain what you observed. This bridges the gap between "following steps" and truly understanding the chemistry happening in front of you.
Balancing equations requires understanding that atoms can't be created or destroyed (conservation of mass) while also tracking multiple elements simultaneously—it's a puzzle that demands both conceptual understanding and procedural fluency. Students often guess-and-check randomly instead of using a systematic method. A tutor teaches the step-by-step algorithm: start with the most complex compound, balance one element at a time, and use fractions if needed before converting to whole numbers. With practice and clear strategy, this becomes one of the most reliable skills students develop in 9th Grade Chemistry.
The mole is fundamentally a counting unit—like a dozen, but for particles (6.02 × 10²³ of them). The key is connecting it to what you can actually measure: mass. A tutor helps you see that molar mass (grams per mole) is the bridge between the macroscopic world you weigh on a scale and the particle world chemists work with. Once you understand that relationship, mole-to-mass conversions, limiting reactants, and percent yield problems become logical rather than mysterious. Visualizing this with concrete examples—like "one mole of carbon atoms weighs 12 grams"—makes it stick.
Since you can't see atoms or electron configurations with your eyes, tutors use multiple strategies: molecular models you can build and manipulate, drawings and diagrams that show electron movement during bonding, animations or simulations that show reactions in motion, and analogies that connect to familiar systems. For example, explaining ionic bonding as "electron transfer" (like trading baseball cards) makes it more concrete than abstract orbital theory. By engaging multiple senses and building from familiar ideas, students develop mental models that make the abstract feel real and predictable.
Strong chemistry tutoring teaches you to think like a chemist: asking "why did this happen?" instead of just "what happened?", predicting outcomes before running experiments, and using evidence to support claims. This means practicing skills like analyzing experimental design, identifying variables, recognizing patterns in the periodic table, and troubleshooting when predictions don't match results. These reasoning skills transfer beyond chemistry to physics, biology, and any field requiring logical thinking. A tutor guides you to ask better questions and test your own understanding rather than passively receiving information.
Unit conversions are the foundation for stoichiometry, gas laws, and nearly every calculation in chemistry—if you can't convert between grams, moles, liters, and particles fluently, larger problems become impossible. Many students memorize conversion factors without understanding them, which leads to errors and confusion. A tutor teaches you dimensional analysis (the "factor-label" method), which is a systematic approach: write what you have, write what you want, and find conversion factors that cancel units until you reach your answer. Once you see it as a logical process rather than magic, you can handle any conversion chemistry throws at you.
If you're struggling, a tutor identifies gaps—maybe you need stronger algebra skills for stoichiometry, or you're missing foundational concepts like atomic structure—and fills those holes before moving forward. If you're doing okay but want to excel, tutoring focuses on deeper understanding, challenging problem-solving, and lab skills that go beyond what's covered in class. Either way, personalized instruction means the tutor adjusts pace and focus to where you actually are, rather than following a one-size-fits-all curriculum. This targeted approach saves time and builds genuine confidence in the subject.
