Allan
12th Grade math Tutor • +85 Subjects
I'm a big Boston Celtics fan and I speak three languages. I can get you the test results you need to succeed because I went through the exams myself and performed well. The first time I took the SAT I actually wasn't satisfied with my score, so I spent 2 months working hard to get my score to where I wanted it to be. The second time I took the exam I saw a 200-point increase. Previously, I have had experience teaching the SSAT and the SAT. The student I tutored in SSAT successfully passed the exam is now attending a private high school abroad. With VarsityTutor's online learning platform, I will be able to transfer knowledge in a visual, easy-to-understand manner. I look forward to being your tutor and helping you reach your academic goals. :)
Priya
Pre-Algebra Tutor • +27 Subjects
I am currently an undergrad at Vanderbilt University, majoring in Mathematics and Political Science. I have been tutoring students since high school, mostly in science and math. I've found that STEM courses are intimidating to many students, and I hope to get rid of that fear and promote an appreciation for numbers and the sciences. In my tutoring, I focus on helping students understand the concepts beneath the problems, so as to facilitate learning rather than memorization. I strongly believe that every student is capable of reaching a strong level of understanding in any subject, given the correct tools, a teacher who can offer what they need, and some hard work. Hobbies: reading, writing, books, music, running, hiking, art, movies

I am currently entering my fourth year of medical school at Perelman School of Medicine at the University of Pennsylvania. I obtained a Bachelor of Science in Biology from Wheaton College in Illinois, where I graduated in 2017 with high honors. Throughout my undergraduate years, I tutored extensively in several academic fields with a focus on the sciences and preparation for the MCAT.
Laura
College Algebra Tutor • +37 Subjects
I am a graduate of Princeton University, class of 2014. I received my Bachelor of Arts in History with a focus on recent American economic history. I was a pre-med, molecular biology major for my first two years at Princeton, and while I ended up deciding not to pursue a career in the sciences, I took many science classes in high school (AP) and in college, and still enjoy these subjects. Since graduating from Princeton, I have moved to Manhattan where I have started a job as an analyst at a private equity firm. I tutored professionally in Princeton for three years, and am excited to continue working with students as a Varsity Tutors tutor. I have experience tutoring elementary school math, Algebra, Algebra II/Pre-calc, English literature, writing (esp. essay editing), Biology (including AP), Chemistry (including accelerated and AP), SAT, and French (through French III). My own educational experience has had a formative impact on my style as a tutor. I attended a Montessori school from pre-school through 8th grade, and was heavily influenced by the focus on independent learning, discovery, and exploration as a way to develop a more thorough and better understanding of academic subjects. I am passionate about making sure that students enjoy what they are learning, and I try to individualize tutor sessions to match the specific needs of each student. Both my parents are teachers (one a violin teacher and another a professor), which has also influenced my ability and desire to help students learn.

Frequently Asked Questions
Students typically find balancing chemical equations, stoichiometry, and limiting reactants most challenging because they require both conceptual understanding and procedural fluency. Acid-base chemistry and equilibrium concepts also trip up many students since they're abstract and counterintuitive—for example, understanding why a weak acid can be stronger than a strong base requires grasping multiple layers of theory. Gas laws and thermodynamics round out the difficult topics because they demand visualization of molecular behavior and comfort with mathematical relationships. A tutor can break these down into digestible pieces and show how each concept connects to the bigger picture.
Many students approach balancing equations as pure memorization, but tutors help students see the underlying logic—that atoms are conserved and you're simply redistributing them on both sides. A tutor can teach systematic strategies like starting with the most complex compound or using inspection methods strategically, then practice problems build pattern recognition. Understanding *why* you balance equations (conservation of mass) rather than just *how* makes the process stick and transfers to more complex reactions like redox equations. This conceptual foundation also makes stoichiometry problems much less intimidating.
Tutors help students see that lab experiments aren't isolated exercises—they're demonstrations of principles that govern everything from cooking and batteries to water treatment and pharmaceuticals. For example, a titration lab becomes more meaningful when students understand it's the same technique used to test water quality or determine medication dosages. A tutor can highlight how the scientific method they practice in lab (forming hypotheses, controlling variables, analyzing data) directly applies to real-world problem-solving. This connection transforms abstract concepts into tangible understanding and makes chemistry feel relevant.
Many students struggle because chemistry requires thinking in three dimensions about particles they can't see. Tutors use multiple strategies—drawing Lewis structures step-by-step, using molecular models or digital tools to show spatial arrangements, and building analogies to everyday objects. For reactions like SN2 mechanisms or hybridization, a tutor can walk through the electron movement and orbital overlap visually, then have students practice drawing these themselves. Breaking down abstract concepts into visual representations helps students build mental models they can apply to new problems rather than memorizing isolated facts.
Unit conversions require students to think about ratios and proportions while managing multiple conversion factors—it's easy to get lost in the mechanics and lose sight of what you're actually calculating. Many students memorize conversion factors without understanding they're just ratios (like 1 mole = 6.02 × 10²³ particles), which leads to mistakes when tackling unfamiliar conversions. Tutors help by teaching dimensional analysis as a logical system where units cancel like fractions, then practicing with real scenarios (converting grams to moles to particles) so students build confidence. Once students grasp the underlying logic, they can tackle any conversion problem, not just the ones they've seen before.
Chemistry rewards understanding over memorization because there are too many reactions and scenarios to memorize—students need to recognize patterns and predict behavior. Tutors focus on building conceptual foundations first (like understanding electronegativity and bonding before memorizing specific compounds) so students can reason through new problems. They also help students ask the right questions: Why does this reaction happen? What would change if we altered temperature or pressure? This deeper thinking develops scientific reasoning skills that transfer across units and even to other sciences. Students who understand chemistry can tackle AP exams and college courses confidently; those who memorize hit a wall quickly.
Beyond content expertise, effective chemistry tutors excel at breaking down abstract concepts into concrete explanations and diagrams—they can explain why electrons behave the way they do or how to visualize molecular geometry. They should be comfortable with the math embedded in chemistry (logarithms for pH, exponentials for rate laws) and able to help students see how equations connect to real behavior. Strong tutors also ask diagnostic questions to uncover misconceptions (like thinking atoms have colors or that molecules are static) and address them directly rather than building on faulty foundations. Finally, they should connect concepts across units so students see chemistry as an integrated system rather than disconnected topics.
Rather than cramming facts, tutors help students identify which concepts are foundational and likely to appear in multiple forms on exams—like bonding, stoichiometry, and equilibrium. They practice working through multi-step problems where students must apply several concepts sequentially (like calculating pH after a neutralization reaction), which mirrors how exams are actually structured. Tutors also help students recognize common wrong answers and the misconceptions behind them, so they can avoid traps on multiple-choice questions. By test day, students aren't just hoping they remember facts; they've practiced reasoning through problems and can adapt their approach to unfamiliar scenarios.
