Jared
12th Grade math Tutor • +124 Subjects
I am passionate about the life sciences and enjoy working with students to help them achieve their goals! I am from Rockland County, New York, and currently work as a Private Tutor and Research Assistant in Ithaca. This January, I graduated from Cornell University with a B.S. in Biological Sciences. I have tutored private clients since 2011 and have experience tutoring students in Biology, Chemistry and Math. I also enjoy helping students prepare for standardized exams for undergraduate and graduate school admission. In addition to my private tutoring activities, I was also a TA to an introductory science course at Cornell. In this position, I lectured weekly to a section of 15 undergraduate students and learned how to engage students in course material. In my free time, I enjoy cooking new recipes, competitive swimming, and tennis. Please feel free to reach out; I look forward to discussing how I can best help your student!

Maria
Pre-Algebra Tutor • +40 Subjects
I have earned Bachelor of Science degrees in both Biological Sciences and Nursing. As a learner, I have always had an inclination toward math and science. I was introduced to the International Baccalaureate (IB) Programme when I was in middle school and I took higher level courses from then until the culmination of high school, at which point I received the IB diploma. I have a very strong academic background, despite the fact that I was always a learner who needed plenty of time and effort for things to sink in. Whenever I had trouble with concepts, particularly in the often challenging subjects of math and science, I wouldn't be open about it with my teachers, usually because of the simple fact that I didn't feel comfortable seeking help. For this reason, what's most important to me as a tutor is that any student I'm helping is comfortable enough to have open communication with me about their concerns and sources of confusion. I also find it very useful (and even necessary at times) to break things down to the very basics, in order to build understanding on a secure foundation. I genuinely love to help people understand whatever is in my power to help them understand, and so it comes naturally to me to take the knowledge I struggled to gain and help someone else along their own path towards understanding.
Brittany
Pre-Algebra Tutor • +37 Subjects
I am a chemistry and environmental science student at the University of Virginia. In high school I completed the IB diploma program and took chemistry, math, english and history at the higher level. I tutor in Middle school math, Algebra 1, Geometry, Algebra 2, Trigonometry, Pre-Calculus, IB Math (HL,SL and Studies), Calculus 1, Calculus 2, IB Chemistry (SL and HL), IB Environmental Systems and Societies, Ecology, and SAT math test prep. I have experience tutoring students in IB courses and non-IB courses. When I tutor I try to lead you to right answer by asking you questions to determine what you already know, clearing up misconceptions, and getting you to think critically about the material. This tutoring strategy is particularly effective for IB exams or application questions that test critical thinking in addition to your mastery of the subject matter. Hobbies: reading, writing, books, music, art, sports
Micaela
Calculus Tutor • +54 Subjects
I am a great tutor, because I am able to craft and implement lesson plans designed for individual students, as well as facilitate group sessions. I have experience teaching Supplemental Instruction at Auburn University, where in addition to lecture materials, I provided study skills and academic success strategies to my students. I am a National Merit and National Hispanic Scholar, and I received a full Academic Presidential Scholarship plus stipends at Auburn. I consistently score well on standardized tests, and I am able to use and share my test-taking skills and strategies.

Frequently Asked Questions
Students typically find equilibrium calculations, organic chemistry mechanisms, and thermodynamics conceptually challenging because they require connecting multiple abstract concepts simultaneously. Balancing redox equations, understanding reaction kinetics (especially rate laws and activation energy), and mastering stoichiometry with limiting reagents are also common pain points. Additionally, the transition from memorizing formulas to applying them in unfamiliar contexts—a key IB expectation—trips up many students who haven't developed strong problem-solving frameworks.
Lab work is crucial—it comprises the Internal Assessment (IA), which accounts for 20% of your final grade, and requires strong experimental design, data analysis, and scientific reasoning skills. Tutors can help you design rigorous experiments, identify sources of error, understand uncertainty and significant figures, and write clear, evidence-based conclusions. They can also help you connect lab observations to theoretical concepts, ensuring you're not just collecting data but truly understanding the chemistry behind your results.
Mechanisms require visualizing how electrons move and bonds break and form—something that's abstract and hard to picture without practice. Students often memorize reaction types (SN1, SN2, E1, E2) without understanding when and why each occurs, leading to mistakes on unfamiliar problems. A tutor can help you develop a systematic approach: predicting mechanism types based on substrate, nucleophile strength, and solvent, then drawing arrow-pushing diagrams confidently. This shifts you from memorization to genuine understanding of reactivity patterns.
Equilibrium problems require fluency with ICE tables, Ka/Kb expressions, and Le Chatelier's principle—but many students struggle because they don't recognize which type of problem they're facing. Tutors break this down by teaching you to identify whether you're calculating pH of a weak acid, finding Kc from experimental data, or predicting shifts in equilibrium. With structured practice, you'll develop pattern recognition so you can quickly set up the right equation and avoid calculation errors that lose easy marks.
IB exams emphasize scientific reasoning and application over pure recall—you'll see questions asking you to predict outcomes, explain mechanisms, or analyze data from unfamiliar contexts. Paper 1 and 2 test conceptual understanding with short-answer and extended-response questions, while Paper 3 includes practical scenarios and calculations. Tutors help you practice explaining your thinking clearly, justifying predictions with chemical principles, and avoiding common reasoning errors like confusing correlation with causation in data analysis.
Thermodynamics requires understanding abstract concepts like enthalpy, entropy, and Gibbs free energy—and then connecting them to predict spontaneity and equilibrium position. Many students memorize ΔG = ΔH - TΔS without grasping what entropy really means or why temperature affects spontaneity. Tutors help by using real-world examples (why ice melts in warm water, why reactions become spontaneous at high temperatures) and building intuition through problem-solving, so you can predict outcomes rather than just plug numbers into equations.
Beyond deep content knowledge, an effective tutor understands IB's emphasis on scientific reasoning and can help you explain your thinking clearly—critical for exam success. They should be skilled at breaking down abstract concepts (like molecular orbital theory or reaction mechanisms) into visual, intuitive explanations, and experienced in helping students design rigorous experiments for the IA. They'll also know the IB syllabus inside out and can identify which topics are frequently tested and which reasoning patterns appear across papers.
Yes—tutors can guide you through the entire IA process: choosing a researchable question, designing a rigorous experiment with proper controls, collecting and analyzing data, and writing clear conclusions that connect results to theory. They can help you identify and quantify sources of error, understand uncertainty calculations, and ensure your write-up demonstrates scientific thinking rather than just describing what you did. This support is especially valuable since the IA requires both strong chemistry knowledge and strong scientific communication skills.
