I dont recomend this product to anyone because it lacks the most important tool crcial to learning. It doesnt show you how to solve the equations now does it give examples of how. Its a disaster unless you are in a chemistry class right now. Then you can use it side by side with your notes. If that is the case the its great. You just cant learn without instructions of how to and where you went wrong. Dont buy, dont buy , dont buy.
