I have been helping science and pre-health students excel for more than two decades. I have spent most of the last 15 years managing the tutoring facility for the Chemistry department at one of the largest universities in the country and continue to work there to this day. I help thousands of students in person in large groups, in small groups, and one-on-one every semester and this site is my attempt to help far more. Chemistry and Physics are not as difficult as you think...I promise! Try one of my FREE or premium courses today! Happy Studying!

Read MoreI purchased this program to study for the ACS final exam for my Ochem 2 class. It has been extremely helpful and has helped me refresh on many of the concepts I had forgotten from Ochem 1. Would definitely recommend. *Update* I ended up making a 97% on the OChem ACS final thanks to this course. Its a must have!

Read MoreJust took my O Chem 1 ACS final today and felt pretty good about it! You are a great teacher and you are the only one that I have been able to actually understand and follow with SN1, SN2, E1, and E2 reactions! Really appreciated the charts and maps you provided! My professor would only show the easiest problems during class so when it came time for the homeworks, quizzes, and tests I felt so unprepared, I wish I found this sooner! My only recommendation is to maybe organize your chapters/videos by Organic Chem 1 versus Organic Chem 2! Thank you for making these videos!

Honestly great Ochem Instructor

His explanations are easy to follow and very clear. He uses analogies to help viewers understand the material. 10/10 best ten dollars we’ve ever spent

Read MoreThis course is a great help for people looking to review their material pre-ACS final or even as a supplemental guide to survive ochem. Due to the bargain pricing, I signed up for 3 months (taking ochem 2 over summer), even though I initially was looking for a ACS practice test for ochem 1, as finals are approaching. Don't have the time? MAKE THE TIME. Chad breaks down each section into mini subsections, so that you can focus on what you need to focus on. It's all in here, but you really can focus on what you need to refresh on pre-final in the minimal time you have left. I've been going through each section and taking the assessment quizzes first, in order to see if I need to review the material the quiz covers. The videos are concise and don't put you to sleep, and the quiz questions have thorough explanations, in addition to video walk-throughs if needed. This is the absolute best deal you will find on a budget and under time restraints. My ochem 1 final is in a few days, and I'm not freaking out about it anymore. For ochem 2, I intend on using this course as a supplement to my [insanely compacted 1-month] course. My only recommendation is for Chad to break down the course into ochem1 and ochem2, so that it can be easier to assess what I need to focus on for the first semester ACS final. I know that that can be difficult, especially since the official ACS practice book does not do that, but it would be greatly appreciated. :)
