About Me

Hi I’m Cate and I am a senior at DePaul studying Health Sciences. Besides being an SI leader for General Chemistry, I also serve as a TA for Organic Chemistry. Currently I work in Dr. Karver’s research lab and I am working on getting into medical school. I really enjoy being able to help students learn the tough concepts in chemistry. I hope this blog will provide useful resources to all my students.


  1. Practice, practice, practice. The more exposure you have to different problems, the more problems you will be able to do.
  2. Make a plan. In chemistry related math problems, you need to be able to get from what is given to you to the answer. What do you know and what do you need to solve a particular problem? I recommend writing out useful equations and underlining information in the problem. Use these to figure out how to solve the problem.
  3. There’s no right way to study. My way of studying may be different from yours and that’s okay. Figure out what study methods work best for you and stick with them. Don’t be afraid to experiment with different study methods.
  4. Check your understanding. The best way to know if you really understand something is to explain it to someone else. Feel free to explain a concept to me!

Videos and Handouts

Don’t forget that Dr. Grice posted a pencast for solving a redox reaction. If you are still confused about the steps of solving those kinds of problems, I encourage you to take a look at it.

Practice oxidation numbers using this link. Simply put your mouse over the formula and it will reveal the oxidation numbers of each element.

This is an overview of the three types of bond theories we have discussed in class. Each one has their place in explaining different properties of molecules. Knowing the differences of these theories will help you on the exam because they can be used for conceptual short answer type questions.

A great way to practice and get to know your molecular geometries is through this website! It’s similar to quizlet except you have to type in your answers. You can practice it over and over again until you have all your molecular geometries memorized. Check out this quizlet test to practice naming and spelling polyatomic ions!



Electron configurations can be difficult. Here is a video that gives a good basis on how to do electron configurations. It will give you a good method on how to go about giving an electron configuration for any element. If you need to practice your electron configurations, but don’t know how to check them, you can use the dynamic periodic table. It gives you every electron configuration and much more. Simply click on the Orbitals tab at the top to find the electron configurations:

This is a link to flash cards and other study methods for atomic theory scientists and their contributions. There will probably be a couple of questions on the exam about these scientists and how they helped to develop atomic theory. Quizlet is a great resource for flashcards since you don’t have to lug them around everywhere. You can always look up a certain topic on quizlet or create your own flashcards on the site. If you love flashcards as a study method, this is a great resource for you! (Also check out the unit prefixes quizlet:

This is about a 5 minute video to show how to work the TI-30X calculator with scientific notation. This is the calculator I recommend using for this class since it is so easy to do scientific notation and will make your ability to take the test a lot easier. If you do not have this calculator, you can easily search youtube to find a similar video that shows how to work scientific notation on your particular calculator. For those who like the guy who made the video, his name is Alan Earheart and he has posted several video podcasts on his youtube website for his general chemistry course at Southeast Community College in Nebraska.
