My Teaching Style
Learning using specially created content. I use my own training content, designed around student needs. We clear basics first, with detailed, easy-to-follow explanations.
Problem-solving to cement understanding. We solve AP-style quizzes at the end of each session. You also get additional quizzes to practice in your own time, and we review them together.
About the AP Chemistry Exam
AP Chemistry is an introductory college-level Chemistry course typically taken in high school. Chemtopper preparation focuses on conceptual clarity, experiment and data interpretation, mathematical problem-solving, AP-style MCQs, FRQs and test revision.
The current AP Chemistry Exam is hybrid digital: students complete multiple-choice questions and view free-response questions in the Bluebook testing app, then handwrite their free-response answers in paper exam booklets.

AP Chemistry Parent Reviews
My daughter went from not enjoying AP Chemistry to topping in some exams , genuinely liking the subject and earning an A, which speaks volumes about Dr. Uma Sharma’s teaching. She explains complex material clearly, engages students, and holds them accountable in a supportive way. Now she wants to study to compete with other kids to answer faster in class. They are very competitive. But I\'m glad they work hard.
We are very grateful for the positive impact she has had on our daughter’s learning and attitude toward chemistry.

We are incredibly grateful to have had such an outstanding AP Chemistry teacher for our daughter. Thanks to her expert teaching and personal attention, our daughter scored a 5 on the AP Chemistry exam!
What truly sets her apart is not just her deep knowledge of the subject, but the way she takes personal care of each student’s success. She was always available to clarify concepts, offer encouragement, and adjust her approach to suit each student’s learning style.
Her passion for chemistry is infectious, and it inspired our daughter to stay engaged and confident throughout the year — even during the most challenging topics. This score is a reflection of her dedicated teaching and unwavering support.
We cannot thank her enough and would wholeheartedly recommend her to any student pursuing AP Chemistry.

Hello Ma\'am! How are you doing? Our amazing Chemistry class together paid off because the score came out and I got a 5 on the AP exam. Thank you so much ma\'am!
My grand daughter needed help in Chemistry for 12+ examination ( 2017-18) in NY. I contacted Dr Uma Sharma & had interaction on how she teaches online; being satisfied we engaged our grand daughter for online assistance. She did very well in her school examination & SAT. Now She has joined University of Chicago. We are extremely happy the way the interaction between our grand daughter & Dr Uma helped to inspire her to work hard & achieve good results.
I am retired Professor from IITDelhi, with my experience can vouch for Dr Uma as a patient & capable Chemistry tutor , who knows how to counsel her students and make Chemistry an interesting subject. Dr Uma is among the best teachers who knows her subject & the art of tutoring!

AP Chemistry at Chemtopper is primarily taught in carefully sized online groups, generally 5–10 students depending on the programme and batch structure. Students who initially prefer one-to-one tuition are encouraged to attend a free 20-minute trial and experience the group format before deciding. One-to-one tutoring is generally intended for college-level Chemistry, subject to availability.
Are AP Chemistry sessions recorded?
Yes. All live AP Chemistry sessions are recorded so students can review the class later on laptop, tablet, or phone. This is especially useful for revising difficult topics and preparing before tests and the AP Chemistry exam.
What practice is included with AP Chemistry classes?
Students receive topic-wise notes, AP-style multiple-choice practice, free-response practice, class-linked quizzes, homework, and test-based preparation. Practice is used to identify gaps and revise weak areas systematically.
How does Dr Uma Sharma teach AP Chemistry?
The method is clear and structured: build fundamentals first, connect ideas with examples, solve AP-style questions, use quizzes to cement learning, and then revise with tests and targeted feedback.
Which time zones do you support?
Chemtopper supports students mainly across the US, Canada, India, Middle East and other international time zones. Available AP Chemistry group slots are shown on this page.
What should a student do if their Chemistry basics are weak?
Students who are new to Chemistry or weak in fundamentals should start with Pre-AP or High School Chemistry support before or alongside AP Chemistry, so mole concept, atomic structure, bonding, reactions, equilibrium and calculations become stronger.
What AP Chemistry results have Chemtopper students achieved?
In 2026, 90% of reported Chemtopper AP Chemistry students scored a 4 or 5. Results shown on this page are aggregate outcomes reported by students or parents.
