What My Students Have to Say

You have made Chemistry so simple for my daughter. She says you are even better than her professor and that her classmates would like to have you as her professor.

Meera, California(parent)

I have gained immense confidence after studying with the tutors on this website. I recommend the tutors here to everyone who needs online tutoring and homework help.

Sarah Hamilton(Math)

My exams had gone off so well after my sessions for MCAT exams with you. I have thoroughly understood Aromatic Reactions, Alkenes and Alkynes after studying with you. Thank you so much. You are the best Chemistry Tutor I have ever had.

Yashika Patel, Boston(MCAT )

You are the best tutor that I have come across in my life. Keep up the good work.

Nick(MCAT)

Dear Uma, We want to thank you for the all hard work you did teaching Felix chemistry: Thanks to your dedicated tutoring he was able to score 760 on his Chemistry SAT test . We are very happy with the test results.

Alex and Katrina Glozman (parents of SAT/AP/general chemistry)

Hi Uma
I got my sat score today. I received a 760 for chemistry. Thank you very much for all your teachings.Under your guidance I will be successful in chemistry..

Felix(SAT Chemistry)

My wife and I will like to thank you for helping our son do so well at AP Chemistry. Although he got a 4, given where you picked him up and the total lack of teaching in his school, the exam outcome was a realistic one.
Mrs. Sharma. my son holds you in very high regard. He describes you as "One of the best teacher in the World " and he says so with a lot of conviction.
As parents we are grateful to you for helping him change his attitude to Chemistry from total fear and intimidation to love for the subject.

Mr P Maitra(Father of AP chemistry student)

Wanted to let you know that Mallika got a 5 on her AP Chemistry exam. Thank you for your efforts.

Radhika Madhusudan mother of AP student

Hello Uma, I just want to let you know that I got accepted to Midwestern University- Chicago College of Pharmacy (my preference) and I also received an invitation to interview at University of Illinois at Chicago College of Pharmacy as well! Both of these schools are the best in my area. I am beyond excited and overjoyed. Of course, it would not have been possible without your assistance and support in organic chemistry. My professors thought that I should pursue advanced organic chemistry or even PhD's- they did not know I worked with a great tutor by my side and that it had made all the difference for me to have met you. My success in my organic chemistry class spilled over to other science classes that I took. I plan to continue working hard and perhaps, very soon, I will need another session with you! Thank you very much again! Sincerely, Cat

Catphuong Nguyen(pharmacy student)

Dear Dr. Sharma, I want you to know that I see you as a mentor. So far, in my life, it has been my mentors who have really helped me, guided me, and I know will mold me even beyond the scope of my career. I will always remember to thank you for all you do. Thank you for all of your help and guidance, Dr. Sharma. Hope you feel better and I will get Sitopladi and Honey :) Kindest Regards, Vinay Sehgal

Vinay Sehgal (organic chemistry student)

Hello Uma, Thank you for your session this morning. My daughter said it was very informative and she learnt well. She said she liked the fact that you asked her questions. Please make sure she understands her basics well, even if it takes more of your time. I have bought a package for 5 hours. As discussed this morning, please schedule the lesson for 8:00 -10:00 am EST tomorrow 3/5. Thank you again for your time and efforts. Vidya

Vidya (mother of Deepika organic chemistry student)

I got my scores-in general chemistry my correct answers were 26 out of 30 questions so my DAT score is 20 out of 30. in organic chem my correct answers were 23 out of 30 questions so my DAT score is 19 out of 30. my average DAT score is 19 out of 30...not bad. we have to see what is the cut off of new york university. it shoud be around 18 or 19 or 20..according to the office people in the university. will come to know in 2013 spring thanks to you for everything..Icouldn't have scored even this much without your help. The overall exam was not that easy..there were some pretty hard questions.specially the PAT section was quite hard when I travel to india this december I will get all the DAT books for you. barrons,kaplan,dat destroyer. thanks again ,will talk when u are free. I was called for interview. will get the result on 3 weeks

Jaspreet (DAT student)

Jaspreet(DAT student)

Hi I am Shah here.I am taking regular tutoring from chemtopper for organic I from uma sharma(tutor).Today I appeared in my final examination and my professor just scanned my answers and told me to get enroll in organic II .This is never heard in USA that a professor asking a student to join a course like this.I think this is something awesome in a student's career .I am really thankful to chemtopper and specially to Uma Sharma (my preferred tutor) who really helped me a lot during my examination time.She helped me understanding organic chemistry in much simpler way by her unique way of teaching.I would like to continue with her as my preferred tutor for organic chemistry II.

Shah (2009)(organic chemistry student)

I had been a novice at Chemistry when I joined Organic Chemistry-I. In my first exam I had got ‘F’ grade and was on the verge of leaving Organic Chemistry when I found you. You have made Organic Chemistry so simple for me. I am now the topper of my class having scored 100% in my exams !!!

Kim Dewitt(organic chemistry student)

In my DAT I was in the top 93 percentile of the US for that section, which means I scored higher than 93% of all test takers. it was all thanks to you Can't tell you how much you helped.

Neha Garge(DAT student)

Hello I would like to thank a very articulate tutor Miss Uma Sharma specifically for helping me with Organic chemistry. Her knowledge of subject is amazing. The way she deals with the topics reveals her deep understanding of the subject. Her encouragement to delve deeper into the subject keeps me flocking into her session. She helps me understand my assignments well so that i am able to work independently. She was never lost for words when questioned, and i always had answers. Miss Uma Sharma is indeed an asset as a tutor. I praise her dedication and genuine love for her profession that was evident in the way she taught.

SHAH Colorado, USA(organic chemistry)

Ms.Uma was very helpful. The active teaching when she asks the student gives the student practice and ensures their understanding which I found helpful.

Neije(Moitreyee)IB student

Uma, Qian transfer from 11th grade to 12th grade on chemistry subject, she was assessed 2 days ago. When I got the news, I want to thank you again for being a very good chem teacher.

Helen( Quian's mother)

I was so happy when I heard my daughter passed AP Bio & Chem both with 4s. Her effort has paid off. I credit Chemtopper for tutoring her. My daughter's school wasn't able to offer AP classes, and I wasn't able to find tutors who taught AP in English in China, so I turned to online AP courses, and I found Chemtopper. Chemtopper's team is wonderful; both our Bio and Chem tutors are PhDs and very experienced tutors. We went through all the content in 3 months and passed the exams with satisfactory results.

Helen Feng(Qian's mother)

just to let you know that Aarti got an offer for a Pharmacy course in London ,King's colleges.She is very excited... she got all the offers from UK thanks for all yr help you gave to aarti she feels comfortable with chemistry

Renuka Patel(mother)

Really good. Tutor was well prepared and explained concepts by using different examples. The sessions are saved so they can be revised afterwards as well. ** HIGHLY RECOMMENDED **

Jamal Ahmed IB chem student

HI Uma ji, I got admission into DDS programme at NYU. Thanks a ton for helping me through and motivating me all the time I wish good luck to you . Your teaching will help make students with a strong foundation God bless you

Jaspreet (DAT student)

Dear Dr. Sharma, Would like to finish chapter 3 in tomorrow's session. I make sure to review notes after our sessions and then go back to re-read the Kaplan book. You are absolutely right: without a complete understanding of the topic, it will be very difficult to grasp the material. Thank you for helping me understand the material so thoroughly.

Vinay Sehgal (MCAT student ))

Dear Uma, My wife and I want to thank you once again for the excellent teaching that you provide to our younger son Thomas. Thanks to your dedicated teaching he, while still in 10th grade, was able to score a 5 in AP Chemistry. You helped him build a solid foundation in inorganic chemistry, and now continue to teach him organic chemistry. He is happy to be your student and we are happy you are his teacher. Sincerely, Ekaterina and Alex Glozman

Alex and Katrina Glozman (parents)

Hi Dr. Sharma, I'm reviewing Orgo Part 2. Everything you taught me is coming back very easily. Once again, thank you! Orgo is 25% of the Biological Sciences section and every point counts. Chemistry is 50% of the Physical Science section so I am making sure to keep up in that area too. Hope you have a safe trip. See you soon. Kind Regards, Vinay Sehgal

Vinay Sehgal (MCAT student ))

A great tutor who enjoys chemistry as well as teaching it. Her teaching style is very understandable and easy. Neither have i had such a good chemistry tutor or have I understood chemistry as much as i did before I started classes with Uma. Couldn't ask for a better chemistry tutor!

Sai Muttavarapu-2013

Great job teaching Organic Chemistry specifically mechanisms of reactions. Thank you.

Felix

After the session I finally understood resonance structures of organic compounds. This is a high yield topic on the MCAT. I wish my college professor could teach as well as Uma.

Felix

I'm in the IB program, and having these online sessions to review for my exams are perfect! Thanks a lot!

Dusan

Really good. Tutor was well prepared and explained concepts by using different examples. The sessions are saved so they can be revised afterwards as well. ** HIGHLY RECOMMENDED **

Jamal Ahmed

It's great that you are so patient in explaining things multiple times and giving extra examples to work out to make sure that I understand the points. Thanks for all your help!

Trevor Poole

Hello ms. Sharma, I wanted to let you know that my ap chemistry exam on monday went extremely well. :) Thank you so much for all the tutoring and help you gave me. I am very pleased with your teaching.... I wish you were my chemistry teacher! My chemistry teacher here was recently diagnosed with ovarian cancer. This is the third time she has gotten the cancer back and there is no guarantee for recovery. But i am very grateful to have come across your website.... I have survived chemistry because of you. Your love for chemistry has inspired me to pursue biochemistry, since i realized through you chemistry is a subject to enjoy and love. Its not just about learning the concepts but actually enjoying them! I am 100% going to continue with your website and teaching for general chemistry and organic chemistry in college. I will have also recommended your website to lots of my friends here. Once again, and never the last, thank you so very much for helping me and guiding me through chemistry. I miss having your sessions at night (over here, for you its morning :). But i will definitely see you in the summer with some more tutoring to prepare me for college! Thanking you, Yours sincerely, Anusha Sent from my iPad

Anusha (AP chem student)

hello ms. sharma! i got my ap scores today and i made a 4 out of 5 on ap chemistry!!!! thank you so much ms. sharma for helping me understand and enjoy chemistry, not just only learning it. i was literally in tears when i saw my score. i have claimed credit for general chemistry I and i will be taking general chemistry II. i have not scheduled for my classes yet.... but i will definitely join chemtopper.com again for chemistry, math and physics. thank you so much ms. sharma....... and i will meet you very soon! yours sincerely, Anusha

Anusha (AP chem student)

Hello Miss Uma, My name is Vivian Jaworsky. I was referenced to you by Dr. Glozman and his sons (Felix and Tomas) who were extremely satisfied with their progress as a result of your tutoring.I wanted to inquire about the tutoring services you provide for both high school chemistry and high school physics. In the past two years I took both courses and I wanted to move on to AP Physics and AP Chemistry in order to prepare for studying pre-med in college. I thought that it would be a good idea to refresh the two basic courses and find out where my weak areas in them are in order to be better prepared to take the AP courses. I was wondering how I could go about doing this with you and how the sessions for both work. Thank You.
