It all begins here; this group of lessons develops the fundamental concepts you will need to get started in Chemistry. Many Chemistry courses skip over most of this material, or at best cover it very rapidly during the first week or two, assuming either that you have seen it all before or that it is so simple that you can get it all out of the textbook. This is fine for those who have lived with this material for some time, but many students have not, or have been away from it for a while. All too often, by the time you realize this, the course has moved on to new material and you never do master these fundamental topics, leaving yourself crippled for the rest of the semester.
These lessons are designed with these problems in mind. Although they
are elementary, they treat their various topics at an adult level of sophistication,
and they are organized in such a way that you can return to them at any
time without feeling talked-down to, and zero in on the particular parts
you need.If at all possible, you will be wise to go thruoghall of the lessons,
in this set, even those whose topics do not appear in your course syllabus.
This is really basic stuff that will find application in all kinds of unexpected
contexts, not only in the course you are currently taking,but also in future
courses in in many aspects of real life.
