Our Purpose

Searching for help takes time. There are so many videos, practice problems, notes, worksheets, and websites to get you through chemistry. CHEMDUNN brings together the best -- giving you the major points for all the concepts, without you needing to spend time searching and trying to figure out what you don't know.

We want you to succeed in chemistry with little to no frustration!  It can be hard enough to think through some of the concepts in chemistry. 

Our Value

Comparable support and tutoring often costs $100+ per hour. CHEMDUNN delivers a more versatile and expanded offering without compromising quality.  We acknowledge that different people, prefer different levels and types of support. Try out something different and cheaper than the traditional "tutor" but equally effective! 

Most of all, we want you to LEARN and take something away from your chemistry studies!
