How's Organic Chemistry Going For You?
If it's going well so far, awesome!
If you have a system for studying organic that works for you, great.
Keep doing what you're doing. Teach it to your classmates. You're winning.
But maybe that's not you... (yet)
Maybe:
- you sit down for a midterm and you blank on how to answer the questions?
- you feel like the course is moving really fast?
- you have a hard time understanding your instructor, or the questions on the midterm seem harder than the practice questions you were given before the test?
Maybe you worry that you might not get a high enough grade for a medical or dental school application, or might not pass the course altogether?
Maybe this isn't your first time taking organic and you're re-taking it and still finding it hard?
Maybe you just avoid studying because you dread the feelings you get when you try to understand the course material, and dread having to tell your family how the course is going and just hope it will all work out somehow if you keep putting it off...?
Yeah. It can be rough.
“I had to retake Orgo 2 at my university because I did very poorly the first time. The course material is difficult and fast-paced, but finding this site made my life so much easier. I used the flashcards & practice problems along with the reaction & mechanism guides in my daily studying. I got an A when I retook!”
Unprompted review · verified on Trustpilot · August 2026You Don't Need To Be A Genius
To do well in organic you don't need to be a genius - you really don't.
But you do need to have the skill of pattern recognition - that means that when you see a problem on a midterm you can quickly come up with a plan for how to solve it.
Think about going into your doctor's office with a sore throat:
- Has your doctor ever seen someone with a sore throat before? Of course
- Do you think they can come up with a plan of attack as to how to figure out exactly what's causing your sore throat within 3 seconds? Yes
- And it's the same if you have any other symptom - back pain, headaches, swollen toenail, you name it - they can quickly come up with a plan because they recognize the patterns.
That's one reason why organic chemistry is a pre-req - because it throws a lot of different types of problems at you and your job is to figure out how to answer them quickly.
If You've Seen A Trick Question Before, It's No Longer A Trick
So how do you learn pattern recognition?
You just have to see a lot of different types of problems.
Yes, it will take work. There's no short cut.
But then, when you sit for an exam and see that weird problem meant to stump your classmates, you will feel calm - because you've had practice working on these kinds of problems before. When others struggle, you can knock it out of the park.
After all, if you've seen a trick question before.... it's no longer a trick!
“This was the best learning aid I had that got me through orgo 1 and 2. The quizzes will not only prepare you for anything your prof throws at you (or the ACS), but the explanations of the answers give a great foundation for any future classes.”
Unprompted review · verified on Trustpilot · 2026Finding Your Study Plan
So how do you find the right problems to study?
Your instructor might tell you to just do all the problems in the textbook, and that's cool, and if you're doing that and it's working for you, great.
Also there are lots of practice exams available for free on the internet and if you're looking at those and doing problems and that's working for you, awesome.
You don't have an infinite amount of time to study organic.
But you probably have time to focus on just the most important questions, right? The questions you're most likely to see on your upcoming test?
And you'd probably want plans and strategies for working through different types of questions so that when you see specific types of problems you know exactly how to think through them and what to do?
You've come to a good place.
“This website was one of the BEST resources I used for organic chemistry 1. My favorite part is how the basics and fundamentals don't get neglected. As a result, reactions are explained by logic and intuition. The explanations are concise and easy to understand. You get your bang for your buck!”
Unprompted review · verified on Trustpilot · April 2026MOC Membership
For a low monthly price the MOC Membership gives you access to 3500+ practice questions many with detailed step by step answers across all parts of introductory organic chemistry
- It's all on one site and is super easy to use (click to flip)
- Quizzes are organized by subject and even embedded in specific articles
- It's like an online textbook that has quiz questions that test you specifically on different concepts and skills you'll learn in organic
You also get printable study guides (PDF) that summarize the whole two-semester course on a few sheets of paper as well as printable flashcards
You can cancel anytime and there's no commitment.
- It's helped students at big state schools, community colleges, Ivy League universities, small state schools, small private schools, online schools, and even high schools
- It's helped people get A's and B's in their organic chemistry courses... and it's helped people to just pass the course and move on with their lives
- It's helped people pass the ACS exam. It's even helped people with the MCAT and DAT.
It's geared for students in the US and Canada but it does help international students too because the key principles of organic chemistry are the same everywhere.
- It has problems that are really simple, and problems that are very hard.
- It has problems that will almost certainly be on your next exam and obviously lots of problems that won't, but are still good practice.
- It has multiple choice problems and short answer problems and mechanism problems and synthesis problems and spectroscopy problems
Just see for yourself - explore the site to see if there's a specific type of problem you're looking for.
If it's a common type of problem on organic chemistry exams, it's probably on the site, and it's constantly being improved every week to make it more relevant and smarter.
If you're not sure you want to pay for something like this, cool. There are over 350 articles on the site that are totally free and whether you want to join is completely up to you. It's not cheap, like a cup of coffee or something, but it's not expensive like an actual physical textbook.

“I was using the site already for the first course but without the membership, and in the past few weeks, I felt like I could gain a lot from the resources provided with the membership, and it was such a game changer.
The explanations of mechanisms, the study sets, & chapter summary sheets helped me get that pattern recognition in this course within a short amount of time. I then found myself having fun solving really hard problems for the first time in this course!
My dream was to make the A cutoff (93%), and I actually ended up making 97%.”

Frequently Asked Questions
Q. How much does it cost?
Three options:
- $12.95/month — recurring, cancel anytime
- $39.95 — one month, non-recurring
- $99 — one year, non-recurring
All three get you the same thing: every quiz, the reaction and mechanism guide, the printable flashcards, and the PDF summary sheets.
Q. Is this useful for the ACS Org 1 or Org 2 exams?
Yes, but the quizzes aren't written as ACS practice exams. They're not timed, and while many hundreds of questions are “ACS-style”, they're not exactly the same format.
What they do cover is the material the ACS exam draws from — both semesters, including spectroscopy — and the ACS rewards the same thing your midterms do: recognizing a problem type fast enough that you're not deriving it from scratch. That's what a few hundred worked problems buys you.
If you want ACS-format practice specifically, the official ACS study guide is the thing to get. Use this alongside it, not instead of it.
Q. I'm not from North America. Can this help me?
Probably, with the caveat that it's written to a US course structure — two semesters, Org 1 and Org 2, in that order.
The chemistry itself doesn't change. Mechanisms, stereochemistry, spectroscopy, and synthesis work the same way everywhere, and the problems are the problems. What may differ is the sequence your course covers them in and how much weight your exams put on each topic.
Everything is priced and billed in US dollars.
Q. Can I cancel my membership myself?
Sure thing. Log in, go to your account page, and cancel there. If it's easier, you can also just email us at support@masterorganicchemistry.com and we'll take care of it.
Only the recurring monthly plan needs cancelling — the 1-month and 1-year options don't renew, so there's nothing to cancel.
Q. If I cancel, will I still have access through the rest of the billing cycle?
Yes. If you sign up on March 1 and cancel on March 3, you'll still have access through March 31. You won't be billed further.
Q. Are the summary sheets included?
Yes. The Org 1 Summary Sheets, Org 2 Summary Sheets, and the Spectroscopy Pack are all included with a paid membership. This wasn't always the case, so you may see older pages saying otherwise.
Not included: the Reagent Guide PDF and the Reaction Maps PDF. Those are sold separately.
Q. What if I lose my password?
Use the "lost password" link on the login page and you'll get a reset email. If it doesn't arrive, check your spam folder — and if it's still not there, email me and I'll sort it out.
Q. What if I pay for this and decide I don't want it?
Reach out within 72 hours and we'll sort it out.
Real Talk: You Still Have To Do The Work
One note, this site doesn't get you out of having to put in the work and we can't guarantee anyone a specific result.
Whatever result you're looking for is going to be related to how hard you work and how many different problems you see.
This site doesn't solve problems for you - but it does make it easier for people to help themselves by putting a lot of different relevant problems together in one place.
But that's probably good, right? I mean you probably want to have a doctor or dentist who put in a lot of work to learn their craft? You want someone who's seen it all before.
And that could be you!
“I took Organic Chemistry 2 over summer semester. While I didn't receive the grade I wanted, there were other factors at play, but I still passed and ultimately that was most important to me. MOC greatly helped me understand the different mechanisms, reagents, and all things we covered over the summer.”
