Does It Matter If Its Expensive?

Does It Matter If It's Expensive?Let me introduce myself, a man of the middle class and my enthusiasm for the book Ted Greene, et al. has brought to the world... 'Chemistry, PDF' by Dr. Deborah Isay.Dr. Isay's methods are a great deal simpler than I would have had them before reading 'Chemistry, PDF'. I would have had to learn through trial and error as well as what I had learned from other teachers I have seen. And, that is just not enough, especially when it comes to this subject! And then, of course, there was the inability to find the time.Dr. Greene, et al. can be a little slow in making their material available to their students. In a way, that is fine. A little impatience does not hurt anyone.What I am questioning is the need for such an expensive course as 'Chemistry, PDF' by Dr. Deborah Isay and Ted Greene. In fact, I have noticed that such courses as those 'Molecular Dangers'Your Life at Risk' by the American Association of Clinical Chemistry are much more affordable.These classes present an easy introduction to chemical preparation that covers all the basics and can be completed in about two hours. To be fair, most of the content of these courses is very similar, but the information is presented in a different format so it can be taught in a shorter period of time.If you are a student of organic chemistry course, I suggest you review the material of 'Chemistry, PDF' before you look for more advanced materials. However, that might be asking too much. It can still be fun to take the easier courses for such subjects as the Introduction to Organic Chemistry and the Organic-Organic-Metabolism course, if you feel it is necessary.I guess I like teaching because I love life science. So, whether a student is very young or very old, I think it is important for a teacher to be able to communicate with students. I think the older teachers are a bit more tired from teaching their students for a long time.Also, I am more likely to try something new with my student s if I have been working with them before. That is why I am more likely to suggest new ways of doing things instead of repeating what I used to do. So, although Dr. Greene is a great choice of author, I do not recommend the more expensive courses.
