Bio Pic for Chad's Prep Homepage-min

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!   -Chad

Video Lectures

Chad's video lectures are designed to present the subject material in as simple a manner as possible.  His incorporation of humor and analogy makes even complex topics both understandable and memorable.

Practice, Practice, Practice

Practice is the most important component in mastering a topic. This is why Chad has constructed quizzes with a progression from easier to more difficult, and from common examples to important exceptions.  This builds comprehensive knowledge of a subject step-by-step and maximizes learning and retention.

Outlines and Cheat Sheets

Comprehensive outlines are provided to facilitate note-taking.  Cheat sheets and summaries are also available for many courses.

"I Love watching Chad's videos. His lectures have been instrumental in re-learning chemistry concepts that I've long forgotten! I especially enjoy how he relates the content with realistic scenarios so that I can understand the content better. The quizzes at the end of each section really help cement the content in. It's even more helpful when the explanation, along with a video is provided for each right or wrong answer. I am extremely grateful and thankful that he not only takes the time to make these videos, but he does it in such a way that it's easier to learn and/or recount past teachings. I highly recommend his videos to anyone and everyone needing refresher's for hard chemistry subjects or for those who want to gain a better understanding of content learned. Thank you so much! You're heaven sent!!!"
