Very helpful course
Very helpful course. I really appreciated the details and overexplaining. However, the excersises were way easier than the ones I have as a university student.

MOC is extremely informative and so so helpful for many subjects, not just ochem — I’ve gone back for reference during biochem and physics too! The thorough explanations completely saved me during ochem 1 & 2.

I used my MOC membership for both Orgo 1 and 2 and it was such a huge help. James has created so many great resources, guides, quizzes and flashcards. I would not have passed Orgo without this!

The site was easy to navigate and provided me with problems and methods to help with O Chem I and II.

I used a combination of this site and another, “Leah4sci”, to get through O chem. I appreciate both of them, recommend both, but this one had really great practice problems where I could see not just the answer but see the steps I was missing when i got something wrong. I had struggled to find that elsewhere and am really grateful I got to get support and practice here.
