Course Description

With almost a decade of experience tutoring OChem I at post-secondary institutions across North America, I have found that the curriculum is similar between many schools (despite the different course codes). This course is an excellent resource for any students taking an undergraduate OChem I course who are looking for a one-stop shop for understanding the core ideas in Organic Chemistry.


This course is not meant to replace your lecture notes! Your professor makes your test, and their lecture notes should be the "ground source of truth". However, my videos and problems are designed to help you build a solid foundation quickly so that you can better understand you lecture notes. Students using this course save countless hours of studying to achieve great grades.


I have had direct experience tutoring the following courses:

UofA: Chem 261

SFU: Chem 281

UofC: Chem 351

Berkeley: Chem 3A

UCSD: Chem 40A

Rutgers: Chem 307

University of Michigan: Chem 210

And more!


The goal of this course is to provide a cost-effective, topic-by-topic resource that you can use in your own time to learn about material before your professors’ lectures, or to help solidify the concepts after them. For each concept, I will go into detail about the material in video lectures, with a focus on the common mistakes and helpful tips and tricks to ensure you have a solid foundation. The layout of the course is comprehensive, and matches the order of the material typically taught, making this a one-stop shop for your needs as a student!

Instructor Details

Jeremy Jerasi

I've tutored organic chemistry and biochemistry for over a decade.


Ever since I took these courses back in 2016, I have not stopped tutoring and helping students get past this notoriously challenging material. In this time, I've earned a masters degree in chemistry and helped publish a few papers. Now, I'm working in the biotechnology industry.


Since COVID, online tutoring has allowed me to help students at over 20 schools in North America. I learned the common curricula shared between many universities, as well as the mistakes and pitfalls that students make across many schools.


My Udemy courses are made for students that might not be able to afford traditional, hourly tutoring.  These courses offer a combined 45 hours of video content, with hundreds of practice problems and solutions.

This was a great course with the most important you need to know about O Chem, it helps you to explore the concepts further on your own if you are interested, great tips are provided throughout the course, highly recommend it.

By John Michael Fox on 6/29/2026

Seems good. his explanations and diagrams are quite good.

By Ogs Onye on 8/7/2025

Good its what i expected .

By Yusuf Cevizci on 3/15/2025

Concepts are explained with more depth and better detail than any in-person lecture. Explains concepts in a logical sense. -For example, instead of memorizing reactions that involve rearrangements, Jeremy shows that as long as a carbocation is present as a reaction intermediate, rearrangements are possible. %70 of studying for my exams was his videos. I found his practice Q's and videos to teach concepts better than a textbook, especially in a limited time frame.

Jeremys course is super helpful for anyone taking Intro Organic Chemistry. He explains concepts very well making organic chemistry a much easier experience. He knows what is generally tested on and gives examples of what he has seen on exams. If you want to do well in organic chemistry I would highly recommend his course!

By Vida Savic on 3/3/2024

This course helps explain all the details about Organic Chemistry my prof misses that end up being important when trying to solve problems on quizzes and exams.

By Selan Turk on 2/25/2024

This was truly an exceptional introductory Organic Chemistry course. Jeremy does a great job at explaining all the concepts simply, and I love how he uses colours to explain exactly what is happening in each reaction. It's very comprehensive, engaging and structured, and split into bite-size video lectures which aid in revision of topics. If you're looking to brush up on your Organic Chem skills, I'd highly recommend checking out this course. Thanks so much Jeremy!

By Hana McEvoy on 12/14/2023

Jeremy is an excellent tutor! I highly recommend his services and this online course to anyone taking Organic Chemistry I. His knowledge and clear explanations helped to simplify very complex topics. I would not have made it through this course if it were not for his assistance.

By Sara Pocrnja on 10/15/2023

Jeremy is the best tutor! He explains everything thoroughly and makes complicated chemistry concepts seem easy. I would 100% recommend him for anyone at the university level who needs help to ace their Ochem exams.

By Fatemeh Ghodsi on 10/3/2023

This course is the perfect match for my ochem needs. Jeremy does an excellent job of explaining complicated topics in easy terms for everyone to understand. Definitely recommend for anyone struggling or needing a refresher.
