### Rescued Me on Equilibrium Test

These videos are terrific. I went from clueless to confident in this Chemistry topic in one evening of watching and re-watching these videos, and scored B on my test (which I was very happy with)!

### The equilibrium online course

I must say I wish I would have purchased the course days prior to my equilibrium exam. The course definitely provided short cuts/Great Hints for figuring out how I needed to solve the problems. Melissa did a great job at explaining equilibrium, K, Q, Kvs, K , ICE/RICE Charts and provided various examples that may be on the test. The 5% Rules of small assumption was probably one of the most short cut/clues that was provided. My instructor never mentioned this in class. Had I know this trick, I would have saved time on calculations or at least knew how i needed to set up my calculations. I would ask to add practice problems where the students need to find Kc, given all [ Initial] and only [1 equilibrium]. Where the given [equil] concentration is to find the change for the other products/reaction by setting up mol to mol ratio.

### Kinetics Notes

I utilized these to help me with my Chemistry 2 exam. I am still using them as I missed my exam and have to make it up. These notes are amazing and have literally helped me completely understand the lesson. I actually use Melissa's notes more than my instructors notes now . My instructor and my learning style are different and Melissa's Notes actually works best with my learning style. I really will be getting more of her notes.

### Current student Taking General Chemistry 102

The videos are easy to follow, and the examples included are helpful. I have a hard time understanding concepts, and the way the material was presented is brilliant. Powerpoint slide lectures can only do so much for a subject heavy with information. The investment is worth it for this resource!
