Organic Chemistry Study Notes, Summaries, and Cheat Sheets

Have you always been dreaming of concise, well written, meticulously color-coded, and carefully designed organic chemistry study notes but never had time to make those on your own? I know the feeling! You probably already know that good organic chemistry notes are essential for passing organic chemistry. Can you imagine not having to worry about making those notes and spending time actually learning? Organic chemistry classes are fast-paced and keeping up with you instructor during the lecture is a challenge on its own. So, if you’re trying to keep up the lecture, then when are you going to have time to organize your notes? Sooner or later you will miss something in class simply due to how fast the teacher is flying through the topics and examples. Then, what happens when you don’t see the mechanism you need in your notes while working on a homework problem? What happens when you are doing the review for the test and re not sure if you’ve gove over everything you need to know? Can you imagine how stressful that would be?

I’ve been teaching organic chemistry for over 15 years and these notes are the result of my teaching experience and the content knowledge. These notes helped hundreds of students all over the world, students who are just like you are doing their best to master organic chemistry. Over the years, I learned what your instructor is likely to ask on the test. Thus I put the things that you need to know to ace your class in these organic chemistry summaries neatly organized in a logical way. You can literally print these notes and go with them to your lectures and take time to listen and follow with the material! Then just add your own example of reactions here and there and you’re done!

Frequently Asked Questions:

  1. Do you have full curved-arrow mechanisms write-ups in your organic chemistry notes?
  2. Do your organic chemistry notes follow any specific textbook? Will they fit my course?
    I do not follow any specific textbook. What I do follow is a typical introductory (sophomore) organic chemistry curriculum. This makes my notes truly universal. I also tend to include additional details to make them more comprehensive.
  3. How are your organic chemistry notes formatted? Can I have them on my phone for a quick reference?
    Yep. These notes come in a pdf format, so they play well with any type of computer or phone you have.
  4. What is the best way to use the organic chemistry notes?
    I purposefully design these notes to be printed so you can add them to your organic chemistry binder. Each reaction/concept takes exactly one or two pages, so you can print out only the pages you need without having to worry about awkward breaks. It takes me over an hour on average to design and draft each page. I do this work so you don’t have to! This way you can use these organic chemistry notes as a “blueprint” for your own study notes and review summaries.
