Best Organic Chemistry Tutor Websites and YouTube Channels in 2024

by Derek Miller 10 min read

Organic chemistry is one of the toughest classes in college, but with a little online help you can master the subject. Here we’ve collected the most popular ochem tutor websites and YouTube channels, and separated them by what they do best. Some have free subject lessons, others offer 1:1 tutoring, and some offer paid downloads for practice exams and cheat sheets. 

One big struggle of new Ochem students is drawing the molecules quickly but neatly. An organic chemistry stencil can be a huge help. We made one that also includes the names of each molecule, equations you need to know, and physical constants for calculations all laser-engraved. It’s only $12.50 and can save you a ton of time - your TA will love grading your immaculate homework compared to the chicken scratch from everyone else!

Most Popular Organic Chemistry Tutor Websites

Let’s start with hard data. We used a special tool to measure traffic to orgo tutoring websites on the first two pages of Google. We excluded tutor-connecting sites like Varsity Tutors. The graphic below shows that the top 3 sites get about 85% of all traffic, but that doesn’t mean you can’t find great value that matches your learning style with the smaller or newer sites.

New vs. established? The fastest-growing sites in the last 6 months are shown below. The upper left quadrant shows the fastest-growing small sites, while the lower left quadrant shows small sites that are not showing much growth.

The top 3 sites anchor the right side with modest changes in traffic over time. ChemistryHall.com is more of a chemistry blog, OrganicChemExplained.com only has a few Orgo posts, and ChemDoodle.com is a great tool for drawing molecules.

Master Organic Chemistry (masterorganicchemistry.com)

With more than 50% of all worldwide traffic, masterorganicchemistry.com takes the cake as the most popular ochem website. It’s easy to see why. James Ashenhurst has a Ph.D. in Organic Chemistry and has been building out this massive library since 2011. The site is completely comprehensive while still being clean, well-organized and snappy fast to load and navigate. 

James’ tutoring site specializes in downloadable and printable study guides and flash cards. “MOC” also has a 180+ library of reaction mechanisms mapped out and 400+ topic-specific blog posts explained with natural-language commentary that’s refreshing compared to textbooks like this Fischer Esterification guide (sample shown below).

The depth to which James covers each topic is unreal. This page on conformations of cyclohexane is just one of hundreds and even cites literature for anyone who wants to go beyond normal coursework. MOC has great free downloadable sample materials to get you started in both semesters of O-chem and get a feel for the style, but you’ll want to buy into the extremely affordable membership ($10/mo) to get his top-tier study guides and practice tests. He also hosts a YouTube channel with 35k subscribers with 14+ playlists separated by topic

Leah4Sci (leah4sci.com)

With 10% of total traffic, Leah4Sci is another powerhouse website in Organic Chemistry. Leah has a different background than the two tutors above: she served in the U.S. Navy as an emergency medical technician including a year in the Middle East, all while getting her dual degree in Chemistry and Biology. Although she has less website traffic, Leah has the strongest YouTube channel of these three with nearly 200k subscribers. 

Leah’s site focuses more on video content where she hand-draws and narrates the reactions like this video series on EAS mechanisms. The videos are hosted on YouTube so you can speed up playback and jump around easily.

She’s also the only top 3 site to offer personal 1:1 tutoring online. There are less expensive options out there (her rate is $175/hr) but you know you’re getting time with someone who’s truly an expert at teaching the material and can integrate your sessions with her supporting material. 

If that’s outside your budget, she also hosts live 1-hr topic-specific “Study Halls” the 1st and 3rd weeks of the month for $79/month, which also buys you the entire Study Hall recording library, practice quiz/exam videos and access to a private Facebook group of students helping each other throughout the semester. 

Free stuff on Leah4Sci:

Paid stuff on Leah4Sci:

  • Private 1:1 online tutoring  ($175/hr)
  • Membership: Live Study Hall and Facebook Group access ($79/mo)

On a final note, Leah’s site is one of the only that adds ACS Exam prep and MCAT prep, which extends into Physics, Biology and Biochemistry. If you’re a pre-med student, this is where you can find everything you need in one place.

  • Victor from organicchemistrytutor.com above also does 1:1 tutoring for $125-$200/hr
  • The Princeton Review offers Organic Chemistry tutoring in an on-demand model. You can hop on and chat about a specific problem with a random available online tutor with no appointment necessary. Tutors have transparent ratings from former students and profiles of their specialties. It’s priced at $30-$40/hr but you may bounce around between different tutors.
  • Varsity Tutors makes you answer some questions about yourself before trying to match you with a good tutor in their database. They have a bunch of O-chem instructors and you can even see their profiles and test scores, but no ratings. It’s basically a match-maker for tutoring.
  • Wyzant has the look and feel of a freelance website, where you search through personal profiles that have ratings, pricing, subjects and total tutoring hours right in front of you. You may even be able to find an ochem tutor near you for in-person lessons. There are currently 365 Organic Chem Tutors available with most pricing from $40-$200/hr. It’s a nice model where you only pay after each completed lesson, with no up-front package commitment. 
  • SuperProf is similar to Wyzant. There are more tutors listed but fewer reviews. Rates for Organic Chem tutors are generally lower than Wyzant tutors, around $15-$50/hr but that could mean lower-quality lessons, depending on the instructor. 
  • Virtual Chem Tutor is a smaller, chemistry-focused site that can connect you with an instructor in their database after you fill out their contact form. Rates are normally $40-$52/hr but you can’t really pick your tutor.
