Learn Organic Chemistry (Orgo-1) with Dr Uma Sharma

Master mechanisms, synthesis and spectroscopy so Orgo-1 feels logical and manageable, not memorisation-heavy and scary.

I am a Certified Online Chemistry Tutor with a Doctorate and M.S. in Chemistry, and more than 30 years of teaching experience.

My method is simple: diagnose your Orgo baseline → build a rock-solid grasp of structure, resonance, and acid–base → drill core mechanisms with worked examples → master exam-style problems and synthesis.

  • Live 1-on-1 & small-group Organic Chemistry (Orgo-1) classes with recorded sessions
  • Concept-first teaching of mechanisms, not blind reaction memorisation
  • Regular practice sets, synthesis drills, and exam-style mocks
Trusted by pre-med and STEM students across the US, Canada, Europe, Middle East and India

The Learning Process with Dr Uma Sharma

YouTube player
  1. Build a deep understanding of structure, resonance, and acid–base ideas before memorising reactions.
  2. Walk through mechanisms step-by-step with curved arrows and electron-flow logic.
  3. Apply concepts to exam-style questions—mechanism, synthesis, multi-step problems.
  4. Use recorded sessions and summary sheets to revise quickly before quizzes and finals.

How to Master Organic Chemistry

To succeed in Organic Chemistry, you need a well-organised approach. The key is deep understanding, not brute-force memorisation.

  • 10+ million organic compounds exist — you cannot memorise them all. Once you know how structures, mechanisms and functional groups behave, new reactions become predictable.
  • Organic Chemistry is rational, systematic and highly organised. When you see patterns in electron flow and stability, the subject stops being scary.
  • Work lots of problems. More practice reveals more mechanism “tricks” and synthesis ideas. You get topic-wise quizzes and mixed practice from my own question bank.
  • Study actively with pen and paper. Draw structures, arrows, and full mechanisms—not just read solutions.
  • Use summary sheets and flashcards. We build concise reaction maps and mechanism cards for quick daily review.
  • Respect the sequence. Each chapter relies on the previous one, so we follow a carefully planned order of topics.

Organic Chemistry Parent & Student Reviews

Hi Dr Sharma! Just wanted to let you know I got final grade for organic chemistry, I got a A!. Thank you so much, couldn’t have done it without your help.  🩷🩷🩷
Hello Dr. Sharma,
Thank you so much for teaching me this semester! I got a 200/200 on my final exam and ended up with an A in the class :) I wish you the best!
Uma,

I hope you\'re doing well. I don\'t know if you remember me but you tutored our daughters in Biology and Chemistry when they were in high school. You\'ll be happy to know that both of them are doctors now!

For a friend of ours, I was wondering if you offer tutoring in college chemistry, physics or calculus classes or if you don\'t, would there be someone you would recommend? Let me know when you can. Thanks.

Hi Dr. Sharma ☺️ I hope you are well. How are you? I have been thinking of you.

I just wanted to let you know I received my final grade in Biochemistry! I got an A ???? I am so grateful and proud. Especially, I am so thankful to you for everything. I won’t be able to express it in words, but thank you for being my teacher, mentor, and source of peace and sunshine. ?

I am kind of in shock about receiving this grade lol. But I wanted to tell you asap. Hope we can call sometime the next few weeks when you are free to catch up.

I have started studying for MCAT and do miss chatting with you about topics. Okay, have a nice day Dr. Sharma! Talk soon ?
Thank you so much for all ur guidance and help Dr. Uma Sharma, I was able to achieve an A in Organic Chem I thanks to all of your teachings throughout the year. Thank you so much and I definetly will seek out your guidance when it’s time to prepare for my MCAT exam
Whatsapp
I just got the result for my organic chemistry final and I got a 93 on the final and ended with an A+ in the class. I wanted to thank Dr.Sharma for all the help as this would not be possible without her. All the best -
Uma Ma\'am is a wonderful teacher. She focuses on concepts and basics, thereby strengthening the foundation and bringing about clarity in the pupil\'s mind .She explains everything in a very nice and engaging manner and patiently clears all the student\'s doubts and queries.With smaller batch sizes, she provides individual attention to each and every student. All in all she is a great tutor and I would gladly recommend her to anyone.
Dr. Uma Sharma is a great teacher. She explains difficult topics in an easy-to-understand way and is very thorough with all of the concepts.
Hi Dr. Uma,

Sorry for such a late mail. I took the chemistry subject tests on Saturday and with your coaching, I think I did very well. There was not a problem that I was unsure of, with maybe 2 or 3 exceptions. Your teaching has always helped me and this time it was of great assistance. Thank you so much!! Expect to hear from me in a few years when I take the MCAT :)

Your Organic Chemistry Questions Answered

Why does Organic Chemistry feel so hard, and how will these classes make it easier?
Most students are overwhelmed by the number of reactions and new language. I break Orgo into a small set of big ideas—structure, acid–base, resonance, mechanism patterns—so you see *why* reactions work instead of memorising every line.
Do you focus on memorising reactions or on mechanisms and concepts?
We always start from concepts: electron flow, stability, and mechanism steps. You will still learn key named reactions, but as applications of a few repeatable patterns (nucleophilic substitution, electrophilic addition, elimination, etc.), not as isolated lists.
Which topics do you cover in Orgo-1?
Typical Orgo-1 coverage includes: structure and bonding, resonance, acid–base, stereochemistry, conformations, substitution and elimination (SN1/SN2/E1/E2), alkanes, alkenes, alkynes, alcohols and ethers, aromatic chemistry, carbonyl chemistry (aldehydes/ketones), and an introduction to carboxylic acids and derivatives.
Will this help with pre-med and MCAT preparation later?
Yes. A strong Orgo-1 foundation makes MCAT organic way easier. We emphasise mechanism logic, acid–base thinking, spectroscopy basics, and functional group transformations—exactly the skills MCAT passages demand.
Do you follow a specific textbook (Klein, Wade, McMurry, etc.)?
I can align to your university text (Klein, Wade, McMurry, Bruice, etc.) and syllabus. My notes sit on top of your book: they condense key ideas, add worked examples, and map directly to the problem sets you are assigned.
How much weekly practice do I need for Orgo-1?
Plan for 3–5 short practice slots between classes. After each session I assign targeted mechanism, synthesis, and conceptual questions. We start every new class by quickly reviewing your doubts from that practice.

Organic Chemistry — Frequently Asked Questions

Do you help with problem sets, quizzes and exam review?
Yes. We use your current problem sets and past exams as a base. I explain concepts, help you start problems, and then gradually move you towards solving exam-style questions independently—without doing graded work *for* you.
What does a typical Organic Chemistry session look like?
Each class has three parts: (1) 10–15 minutes reviewing your doubts and last assignment, (2) 35–45 minutes of concept + mechanism teaching with worked examples, and (3) 15–20 minutes of exam-style practice plus a quick summary sheet of key take-aways.
Are the classes 1-on-1 or small groups?
Both. Many Orgo-1 students start 1-on-1 to fix core gaps and then join a small group (≤5) for regular classes. Group students can add optional weekly 1-on-1 time for tough topics or exam prep.
Are sessions recorded and can I re-watch mechanisms later?
Every session is recorded and shared, so you can re-watch tricky mechanisms (like SN1/SN2 vs E1/E2 or aromatic substitution) at your own pace on phone/iPad before quizzes and exams.
Do you provide notes, mechanism maps and practice worksheets?
Yes. You receive concise notes, reaction maps, mechanism step-flows, synthesis drills, and exam-style problem sets. Before tests we switch to mixed-topic worksheets and timed practice.
Which time zones do you support and how can I schedule a trial?
I regularly teach students in US/Canada, Europe, Middle East, and India time zones. Use the Free Trial link or registration page to share your time preferences; we finalise a fixed weekly slot over WhatsApp/email.
